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.
The profitability of cannabis testing hinges on rapid sample turnaround and result delivery. However, the complexity of test requirements is increasing. To maintain quality and gain a competitive edge, labs must embrace digital transformation and adopt more efficient, accurate, automated, and scalable testing methods.

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?
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.
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.
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. One of the instrument that proudly carries this label is the versatile Agilent 1260 Infinity II LC System.
At every step, it is critical that lab technicians and support staff are educated and share the responsibility for using new technology and implementing sustainability policies. Having goals is essential, but they cannot be achieved without the collective efforts of the staff. They need to understand how to properly dispose of plastic waste, implement practices to reduce water and energy consumption and be inspired to seek new ideas and solutions to help labs achieve their sustainability goals.
Companies like Chemetrix and its suppliers, such as Agilent, provide a wide range of resources to support this educational effort. By fostering a culture of sustainability and equipping staff with the knowledge and tools needed to make a difference, labs can significantly reduce their environmental impact while continuing to advance scientific research.

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:
Nutrition — ensuring the required nutritional value of milk is present in its products.
Safety — confirming the absence of suspected harmful chemicals in milk.
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).
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.
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.
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, theAgilent 8890 GCand 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.
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.

In the realm of pharmaceutical, medical device, and biotechnology industries, ensuring product safety and compliance with stringent regulatory standards is paramount. One of the critical quality control processes that aid in achieving this goal is bioburden testing. This essential procedure involves the quantification and identification of microbial load on products, packaging, and raw materials. At Chemetrix, we understand the significance of this process and the need for reliable and efficient instruments. This is where Veolia’s advanced solutions come into play, providing robust support for bioburden testing to enhance quality control measures.
What is bioburden testing?
Bioburden testing is the measurement of the microbial load, or the number of viable microorganisms present on a product, surface, or in a solution. This test is crucial in various stages of manufacturing, particularly for sterile products, as it ensures that the bioburden levels are within acceptable limits before sterilisation. By identifying and quantifying the microorganisms present, manufacturers can assess the effectiveness of their cleaning, disinfection, and sterilisation processes.
The results from bioburden tests are used to validate and monitor the manufacturing processes, ensuring that they consistently produce products that meet safety and efficacy standards. Regular bioburden testing helps in detecting contamination issues early, preventing potential product recalls and safeguarding consumer health.
The necessity of bioburden testing in quality control
Bioburden testing is not just a regulatory requirement but a critical aspect of quality control that offers numerous benefits:
Ensures sterility: For products that must be sterile, such as medical devices, pharmaceuticals, and surgical instruments, bioburden testing ensures that the sterilisation processes are effective. Any surviving microorganisms can pose serious health risks to patients.
Regulatory compliance: Regulatory bodies like the FDA and EMA mandate bioburden testing as part of the manufacturing process. Non-compliance can lead to severe penalties, product recalls, and damage to a company’s reputation.
Process validation and control: Bioburden testing helps in validating and controlling manufacturing processes. By understanding the microbial load at various stages, manufacturers can fine-tune their processes to minimise contamination risks.

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.
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.
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.
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.
Although PFAS research on the African continent is not extensive as yet, the growing awareness and need to understand these chemicals for policy and regulation is necessary. As an analytical instrument supplier and solutions provider for laboratories, Chemetrix is committed to helping combat the “Forever Chemical” challenge.
