Harnessing AI for Next-Level Quality Assurance

While it can seem like Artificial Intelligence (AI) is a fancy tool only applicable in certain industries, AI is closer to you than you might think. From social media to your streaming service, AI processes are assisting with data processing and management in all sorts of innovative ways.

As the modern lab continues to evolve, AI adoption is becoming more commonplace. The increasing demand for accuracy but also shorter turnaround times has laboratories seeking technological and often digital solutions to help them achieve their business and operational goals. Lab analysts needn’t fear, AI isn’t coming for their jobs, but what it can do is support the work of lab staff to boost efficiency and ensure that quality control is optimised.

Quality assurance in labs

The quality assurance processes in labs are all about ensuring that the laboratory’s procedures, data analysis and results are of the highest quality. Without good quality assurance, there is a far higher probability of errors which can affect the results delivered. This can have a direct effect on product research and development, the development of environmental management solutions, and the manufacturing of products.

In testing labs, the integrity of samples is paramount in the quality assurance process. A good quality assurances process will make sure the samples aren’t compromised, which can lead to costly setbacks. Of course, good quality assurance means that the results from the lab can be trusted and they are reproducible. As laboratories seek to build strong relationships between themselves and stakeholders, good quality assurance provides quantitative and qualitative evidence of why the lab can be trusted.

Finally, safety also forms part of lab quality assurance. The process should make sure all the equipment is functioning properly and that proper procedures are documented and followed for handling samples, hazardous materials, and chemicals. By doing this, labs can prevent minor accidents that could lead to bigger safety risks.

Levelling up with AI for QA

AI opens a world of possibilities for the modern laboratory. Because of the big volumes of data and frequent tests and analyses, labs can benefit quite a lot from AI and machine learning. Traditional lab operations often involve repetitive and time-consuming tasks such as data backups, data review, and preliminary analysis. By automating these tasks, AI allows scientists to focus on higher-value activities such as experimental design, interpretation of results, and innovation.

In terms of quality assurance, there are a few key benefits from utilising AI:

Greater speed without greater risk of errors – The speed at which data can be processed and reviewed using AI significantly reduces the overall time required to complete experiments and projects. This acceleration in the workflow is crucial for meeting tight deadlines and maintaining competitive edges in research and development. Furthermore, AI’s ability to quickly analyse vast amounts of data helps in identifying trends and anomalies that might be missed by human reviewers. This enhances the accuracy and consistency of repetitive tasks, ensuring that data is reliable and free from human error.

Cost management – Automation of tasks is one of the big advantages of AI and this can assist with cost management by potentially reducing overtime or weekend work hours, which aids operational costs. The resources saved from routine tasks can be allocated to more strategic investments and research, and this includes the brain power of key laboratory staff. Laboratories can also expand their capabilities without a proportional increase in manual workload and this assists labs in scaling their operations up without greater cost pressure.

Optimise resources – AI systems can do real-time monitoring of experiments and equipment to provide immediate feedback should a problem arise. It also means staff don’t have to be in the lab watching over the analytical instruments all the time, particularly if it requires hours before there are results and they could monitor the process remotely. This improves safety and resource management. AI can also assist with efficient resource management to reduce waste and lower the overall environmental impact while simultaneously checking instruments for preventative maintenance.

The cannabis industry is rapidly evolving, and with it comes a multitude of opportunities and challenges. The South African cannabis industry is also booming, driven by increasing demand for both medicinal and recreational cannabis products. Companies are developing various cannabis products, including oils, tinctures, and edibles. But this also means, as cannabis becomes more accepted and regulated, the need for accurate testing services grows.

A common misconception is that the sector is a straightforward cash cow for businesses, particularly in the realm of cannabis testing.

With regulatory requirements mandating thorough testing and the potential for high-profit margins, it might seem like a low-risk venture. However, newcomers should be cautious of pitfalls that can derail less experienced operators.

Quality in cannabis analysis

One of the most critical aspects of succeeding in cannabis testing is recognising the importance of quality. Setting up a laboratory with a strong emphasis on quality is not merely a regulatory necessity but a cornerstone for running a successful business. Quality in this context involves ensuring equipment reliability, accuracy and timeliness of results, staff training, reagent preparation, and method validation. By prioritising these elements, laboratories can minimise errors, enhance their industry standing, and build a solid reputation with customers.

Watch our webinar on Promoting Cannabis Lab Success >

 

Implementing a robust quality management system (QMS) is central to the operation of a high-functioning cannabis testing laboratory. A well-executed QMS produces high-quality, traceable data that stands up to audits and can be scrutinised if complaints arise. This system should be an ongoing effort to refine documentation practices, reduce errors, and improve testing processes.

Part of quality management is implementing the most effective methods for testing. eMethods are designed to accelerate your startup time by condensing the vast amounts of technical information and optimised analytical methods into a ready-to-run, downloadable, digital information package. What’s even better is that Agilent has done the hard work for everyone by creating eMethods that provides information on the instrument configuration, consumables, and Sample Preparation Protocols. eMethods also provide analytical methods for sample introduction, chromatographic separation, detection, and data analysis.
Compared to starting from scratch, an eMethod gives your lab a head start and gives you tips and tricks for best practices across all aspects of your workflow. If your lab is testing for pesticide residue, for example, an eMethod supplies the method for the separations and reliable detection of 72 pesticides and 5 mycotoxins in under 8 minutes.

Of course, you need great analytical instruments on which to run those methods. For new labs or labs moving into cannabis testing, it’s worthwhile to explore the latest technology in instruments. There’s great interest in ICP-MS which enables the analysis of trace metals in complex samples. As an example, The Agilent 7900 ICP-MS system helps you screen for target compounds in complex matrices – all within a single analysis. There are important questions to ask of an instrument supplier like Chemetrix when looking at the instruments for cannabis testing, like if sample types are measured, calculating the eventual cost per sample, if the software suits the instruments, and what technical support is offered. Chemetrix is able to provide confident answers to all these questions and more.

Imagining the Zero Waste Labs of Tomorrow

Scientific research laboratories play a crucial role in advancing our understanding of science and developing transformative healthcare solutions. However, the intensive nature of lab work has raised concerns about their environmental impact. These concerns primarily focus on energy consumption, waste production, chemical handling, and equipment disposal, all of which can leave a significant environmental footprint.

Life science research, in particular, is known for its high consumption of water and energy. Labs dedicated to addressing some of society’s most pressing challenges generate a disproportionate amount of waste. According to a study from the University of Exeter, nearly 5.5 million tons of plastic waste originate from labs, accounting for approximately 2% of all plastic waste globally.

In an era where global sustainability is of increasing importance, labs are facing the challenge of balancing scientific progress with ecological responsibility. Encouragingly, significant strides are being made in this area. A recent survey on lab sustainability by Frost & Sullivan revealed that 82% of the labs surveyed have adopted sustainability metrics. Impressively, 92% of these labs use these metrics to monitor resource use, and 87% have committed to goals aimed at reducing their global greenhouse gas (GHG) and carbon emissions. So, what are some of the key moves these labs are making to achieve these goals?

Reducing waste in labs

Waste management is a major environmental concern, with many labs recognising the need to reduce waste production. They are finding that even small, straightforward behavioural changes can lead to substantial results. Managing plastic waste, in particular, is a critical issue for labs.

Traditionally, plastic waste in labs is sterilised, incinerated, and transported over long distances, significantly contributing to carbon emissions. Furthermore, the incineration of plastic releases numerous toxic chemicals into the environment.

Watch our webinar on Boost Productivity and Eliminate Waste in Raw Material ID >

Fortunately, the market is seeing the development of innovative solutions for better plastic waste management in labs. One such solution is a sterilisation process that is over 90% more carbon-efficient, using a combination of mechanical and chemical processes. This innovative process eliminates the need for autoclave sterilisation, which disinfects plastic waste using heat—steam—along with pressure and time.

Real-time monitoring of lab assets

Enhancing the management of lab systems and processes presents a promising opportunity for innovations that leverage the rapid advancement of digital tools. The cost-effectiveness of data monitoring and collection across various analytical instruments, along with the implementation of technologies such as artificial intelligence (AI) and machine learning (ML), can optimise asset usage and improve overall lab efficiency.

Future lab instruments will likely be equipped with features for monitoring and providing real-time feedback on their operational status. They will have built-in intelligence to alert lab technicians if there is an operational issue that needs attention or if consumables are running low. This real-time data will enable operators to make better-informed decisions, thereby optimising their lab assets for efficient management, superior scientific output, and sustainability benefits.

It is also important to analyse a lab’s end-to-end supply chain to ensure suppliers are being engaged that share similar sustainability values and provide transparency on their sustainability performance. Such choices are made easier by My Green Lab’s ACT label which provides information regarding the environmental impact of manufacturing, using, and disposing of a product and its packaging.

How Real is Your Milk?

The African dairy market is on the rise. Southern Africa plays a crucial role in this growth, with milk consumption gradually increasing in the region. Milk is a staple food in this region and is consumed in various forms, including fresh, powdered, and condensed milk.

The growth of the African dairy market is driven by factors such as changing consumer preferences, increased demand, and local special circumstances. The International Finance Corporation (IFC) projects that the African dairy sector will continue to grow by 30% which is drawing attention from investors.

Milk: The essentials

Milk is a natural source of the fats, minerals, nutrients, micronutrients, and vitamins required for a balanced diet. It is also essential for the growth and development of babies and infants into early childhood. Either breast or infant formula milk is given to babies for at least the first six months of their lives, and between the ages of one and two years, whole milk and dairy products are recommended to ensure that babies receive essential vitamins they may not otherwise obtain from lower fat alternatives.

 

Preserving nutritional values, safety, and authenticity

Milk and its related products are tested for three main reasons within the food and beverage industry:

  1. Nutrition — ensuring the required nutritional value of milk is present in its products.
  2. Safety — confirming the absence of suspected harmful chemicals in milk.
  3. Authenticity — determining if milk products are adulterated and therefore compromised in any way.

By testing these three factors, consumers are more protected from mislabelled, fraudulent, and potentially contaminated milk products that may have reached the marketplace unregulated.

The importance of testing nutritional values of milk and infant formulas

Testing the nutritional values of milk is important so that consumers can make informed decisions about their purchases. Above all, manufacturers of specified products — such as infant formulas for example — must adhere to uncompromising nutritional values determined by regional, national, or international regulatory bodies.

To support consumers making these decisions about their milk and/or infant formula purchases, it is crucial for manufacturers to label their products accurately. In doing so, food testing labs may carry out experiments using HPLC, LC/MS/MS, and GC systems to accurately measure milk content for sugars, fats, vitamins, and amino acids.

Measuring the levels of vitamins as well as beneficial (and some essential) elements such as sodium, potassium, magnesium, calcium, selenium, phosphorus, manganese, and zinc, provides insightful nutritional information. It’s also important to monitor for potentially toxic elements such as arsenic, cadmium, tin, mercury, and lead in animal-derived milk as contamination could originate from animal feed, fertiliser, soil, or processing equipment.

In one study, the Agilent 5800 VDV ICP-OES system used with an SPS 4 autosampler determined calcium, copper, iron, potassium, magnesium, manganese, sodium, phosphorous, and zinc in milk powder and infant formula samples according to the ISO 15151 method. Results showed that the recoveries for all analytes with certified or reference values were within ±10% of the expected value, thus confirming its nutritional labelling.

Other experimental examples include the rapid analysis of major and trace elements in milk and milk products using an Agilent 7900 ICP-MS with optional Ultra High Matrix Introduction UHMI technology and Integrated Sample Introduction System (ISIS 3).

Examining the safety of milk

Foods of animal origins such as dairy milk go through additional scrutiny to detect levels of veterinary drugs. Without a sophisticated approach for testing dairy milk samples, analytical challenges are likely to arise due to the complexity of the matrix and the number of pharmaceutical analogues needed to monitor. Furthermore, the different legislative requirements of various countries require sample referencing that meets a wide variety of regulatory conditions.

Watch our webinar on Food Testing Using Atomic Spectroscopy>

Another factor to consider when examining the safety of milk is the responsible use of pesticides within established limits in animal feeds from which dairy milk is extracted, and in other plant-based ingredients which may be added to other milk products. To validate this, LC/MS, GC/MS, and Q-TOF workflows offer food testing labs the solutions needed to accurately measure pesticide levels in milk samples.

Furthermore, food safety studies are routinely conducted to detect, quantify, and validate trace-level analysis of undesirable byproducts such as chlorate and perchlorate in store-bought milk and infant formulas. In one particular study, the Agilent 1290 Infinity II LC and Ultivo triple quadrupole LC/MS (LC/TQ) were utilised. Data from this experiment highlights accurate quantitation at one-tenth the level of the maximum residue level (MRL), which is 10 μg/kg in milk and infant formula as defined by the European Commission.

Agilent Ultivo LC/MSMS

Exposing fraudulent milk to preserve its authenticity

Globally, milk continues to be one of the most adulterated food and beverage products on the market. For example, in 2008 the analysis of dairy milk powder from Minhe Hui County, China, revealed the contamination of melamine—an organic compound used to manufacture fertilisers and concrete—to be 500 times the maximum limit of melamine found in test samples at that time.

More recently in Southern Asia, the Punjab Food Authority seized almost 80,000 litres of milk to combat the adulteration of dairy products in the local metropolis. The milk was flagged due to the addition of urea and water.

In addition to deceiving consumers and manufacturing producers, food fraudsters can seriously affect the health outcomes of individuals. Fortunately, innovations in analytical instrumentation and testing methods are exposing these unlawful acts to reinstall consumer confidence by validating the authenticity and safety of products such as milk and infant formulas.

For example, the Agilent 8890 GC and the Agilent 5977B GC/MS single quadrupole mass spectrometer have been used to detect and quantify β-sitosterol in ghee (milk fat) samples to check for vegetable oil adulteration. The presence of β-sitosterol is associated with low quality and is a potential indicator of adulterated milk. Results showed that 2.24 ppm β-sitosterol was found in the ghee sample on which the study was performed.

Agilent 8890 GC

Both targeted and non-targeted approaches can be used to identify known compounds in milk and other food authenticity testing. The latter is beneficial if adulterants in milk are new or have not been previously identified by food testing labs. Non-targeted methods using quadrupole time-of-flight mass spectrometers, for example, create a chemical fingerprint of authentic foods, making it more difficult for food fraudsters to cheat the global food supply chain.

 

Forming partnerships to eliminate milk fraud

As milk sale projections are estimated to increase over the next few years, and with wider varieties of product choices in stores and online, it is important that companies like Chemetrix continue to work in partnership with its food testing customers to eliminate the threat of milk fraud while preserving its nutritional values, safety, and authenticity. Above all, manufacturers of milk products must adhere to multiple food regulations relating to quality and safety which are constantly being updated. Chemetrix is here to support our customers so that consumers of their products have confidence in their purchase choice for the nourishment of themselves and their families.

Combating PFAS ‘The Forever Chemical’ Contamination

Per- and Polyfluoroalkyl Substances (PFAS) are a group of manufactured chemicals that have been used in industry and consumer products since the 1940s due to their useful properties. There are thousands of different PFAS, some of which have been more widely used and studied than others.

Nothing about PFAS – from how they are made, to their unique characteristics, to how they need to be analysed – is easy. These chemicals were developed to simplify our lives, but now decades later, they have become a serious problem due to their elusive and persistent nature, hence the nickname ‘The Forever Chemical.’ What is clear is that PFAS contamination is an environmental and growing health issue, but what is less clear is how to address and manage this issue.

 

The importance of PFAS

PFAS are important because they have been widely used in industry and manufacturing due to their unique chemical properties; properties that make them heat-resistant, able to repel water, and close to indestructible. PFAS compounds have been used in many applications such as non-stick cookware, stain-repellent clothes, food contact materials, detergents, cleaning products, and fire-fighting foams.

The unfortunate consequence of PFAS

For many years, PFAS were thought to be inert and nontoxic and were extensively used with little thought for environmental disposal or ecological impact. It was not until early this century that the extent of PFAS global contamination was first realised. There are over 4000 PFAS compounds thought to have been manufactured and are now potentially in the environment globally.

The research on PFAS compounds has identified them as being persistent and bio accumulative, and their widespread use has led to them being almost ubiquitous in the environment. Because PFAS do not break down, they enter the environment through production or waste streams. In South Africa, the presence of PFAS has been detected in some water sources, including rivers and dams.

“PFAS are a new style of pollutants that don’t follow the ‘rules’ of traditional organic pollutants. This is why regulators and scientists, unfortunately, failed to predict how these chemicals would move through the environment, and why we now have a serious problem of such widespread PFAS contamination of drinking water, agricultural land, and the domestic environment.”

– Bradley Clarke, senior lecturer in Analytical Chemistry and Environmental Science, at the University of Melbourne in Australia, and an Agilent collaborator.

 

PFAS exposure and human health

People can be exposed to low levels of PFAS compounds through consumer products that contain PFAS, for example, carpets, leather and apparel, textiles, paper and packaging materials, and non-stick cookware. Drinking water can also be a source of exposure in communities where these chemicals have contaminated water supplies, such as an industrial facility where PFAS were produced, or used to manufacture other products, or an oil refinery, airfield or other location at which PFAS may have been used for firefighting.

Download our eBook Guide to Targeted Quantification and Screening of PFAS Compounds in Environmental Matrices >

Helping scientists learn more about PFAS

PFAS contamination is a complex issue. While knowledge about PFAS compounds and their potential health effects has grown, many questions remain unanswered. It’s also a global issue and collaborative research allows countries to share knowledge, best practices, and effective solutions.

Watch our webinar on Strategies to Optimise Performance of PFAS Analysis >

Committed to helping scientists and regulators around the world solve these water issues to provide safe and sustainable water sources for everyone, Agilent has recently developed a protocol for the analysis of PFASs in drinking water using the Agilent Ultivo triple quadrupole LC/MS. Working with leading researchers around the world, Agilent has also developed a method for extracting PFASs in drinking water using Agilent Offline Solid Phase Extraction and an Agilent LC/MS/MS system with a PFAS-free 1290 Infinity II LC System.

Agilent Ultivo LC/MSMS

Providing scientists with measurement and identification technology solutions to accurately analyze PFAS chemicals in water is a critical first step for estimating human exposure and potential risk. Robust analytical techniques that can provide unbiased quantitative and qualitative data on these PFAS pollutants at trace levels are necessary for further understanding their environmental fate, ecological impacts, and impacts on public health. These analytical techniques and the fundamental data they generate will allow scientists and regulators to make informed assessments of PFAS use in modern society.

Revolutionising Nutrition: The Rise of Alternative Proteins

The food industry is experiencing a significant shift as alternative proteins rise in popularity. These non-animal-based foods, ingredients, and beverages, including plant-based, cell culture-based, and fermentation-based proteins, offer a new frontier in nutrition and sustainability. Designed to mimic the taste, texture, and nutritional profiles of traditional animal proteins, alternative proteins have come a long way from the mock meats of the past. The market for these products is booming, projected to surpass $290 billion by 2030, driven by their nutritional benefits, environmental sustainability, and potential to enhance food security.

Today, the industry for alternative proteins has technology on their side and are continuously turning to data and analysis to find solutions that will make these increasingly popular food items more appealing to a wider consumer base. And while meat or burgers grown in a lab does grab headlines, it’s a far cry from the products found in grocery stores that are more practical and cost-effective. Making better alternative protein products isn’t as easy as throwing lentils into the mix and scientific methods are helping to expand the alternative protein offerings in the mainstream market.

 

Passing taste tests with lab innovation

As the market for alternative proteins expands, rigorous testing becomes crucial. Ensuring the safety, composition, health benefits, and sustainability of these products is essential for maintaining consumer trust and industry growth. For many consumers, concerns about contaminants like veterinary drugs and hormones in meat products make alternative proteins a preferred choice, perceived as a healthier option. However, with rising demand and sometimes limited supply, food fraud becomes a significant challenge. Fraudsters may substitute expensive plant-based proteins with allergens like wheat or soya, or engage in other deceptive practices such as mislabelling and counterfeiting.

To address these challenges and meet consumer expectations in terms of the sensory experience, food developers are turning to advanced analytical tools. These tools are essential for overcoming the biggest hurdles to mainstream acceptance of alternative proteins: taste and texture.

By using sensitive instruments to analyse and optimise the flavour, aroma, and nutritional profiles of these products, food scientists can ensure they meet the high standards expected by consumers.

The process begins with sample preparation to remove unwanted interferences such as fats, chlorophyll, and pigments, allowing researchers to accurately compare the alternative proteins to their animal-based counterparts. Tools like liquid chromatography and mass spectrometry systems are then used to analyse food on a molecular level. Liquid chromatography provides detailed characterisation of stable components such as amino acids, vitamins, and lipids, while gas chromatography examines volatile compounds to engineer desired smells and tastes.

In addition to instrumental analysis, human taste testers play a crucial role in evaluating the palatability of food. Advanced instrumentation can complement this by objectively identifying the five basic tastes – sweet, salty, sour, bitter, and umami – in alternative proteins. This combined approach ensures a comprehensive assessment of flavour and texture, critical for consumer acceptance.

Ensuring a quality composition of alternative proteins

Agilent’s workflow solutions exemplify the robust testing needed in the alternative protein industry. These solutions validate the authenticity, nutritional information, and safety of alternative protein products. For instance, Agilent’s LC-Q-TOF-MS/MS technology has been used to investigate non-meat proteins and peptide markers in ready-to-cook beef burgers, while GC/MS-based metabolomics approaches differentiate the chemical profiles of plant-based meat alternatives from grass-fed ground beef.

Elemental analysis is another critical aspect of ensuring the quality of alternative proteins. During the production process, there is potential for elemental metals to contaminate the final products. Agilent’s atomic spectroscopy instruments, such as the 7850 inductively coupled plasma mass spectrometry (ICP-MS), enable the identification and quantification of these metal elements, ensuring product safety.

The future of food relies heavily on advancing research into alternative proteins. Technologies such as ICP-MS, triple quadrupole (QQQ) liquid or gas chromatography-mass spectrometry (LC/GC/MS), and high-performance liquid chromatography (HPLC) are recommended for robust testing purposes. These tools not only support the development of safer, healthier, and more sustainable food options but also influence the global food supply chain.
