At Chemetrix, we have been an authorised Agilent distributor in Southern and East Africa for decades. While our heritage is diverse, our commitment to the pharmaceutical sector is foundational. We don’t just supply instruments; we provide the technical scaffolding that allows pharmaceutical analysts to move from a raw sample to a validated report with total confidence.

Why great hardware isn’t enough

One of the most persistent challenges in the pharmaceutical workflow is the transition from a concept to a robust, validated method. It is a common misconception that high-end instrumentation automatically guarantees ease of use. In reality, pharmaceutical analysts often struggle with the “blank space” between unboxing an instrument and running their first compliant sample.

Whether you are identifying trace impurities, performing stability testing, or conducting complex bioanalysis, the method development phase is often where projects stall. A method that works in a controlled environment can fail in a high-throughput production setting if it hasn’t been stress-tested for robustness. This leads to a reactive cycle of troubleshooting and re-validation, which drains resources and delays time-to-market.

Navigating a shifting regulatory landscape

Data integrity is the non-negotiable cornerstone of the pharmaceutical industry. Global research shows that 90% of pharmaceutical professionals agree that reliable instruments are the single most important factor for a successful workflow. This is because, in this sector, a failure in reliability is a failure in compliance.

The pressure to process more samples while maintaining absolute adherence to 21 CFR Part 11 and EudraLex Annex 11 is immense. Without a partner who understands the nuances of IQ/OQ (Installation and Operational Qualification) and ongoing maintenance, labs risk falling into the “efficiency gap.” This is where sophisticated instruments sit underutilised because the method is too temperamental or the staff lack the specific training required to navigate the software’s compliance features.

Mastery of complex matrices with Agilent LC/MS

For laboratories tackling the most demanding pharmaceutical applications – such as nitrosamine analysis or impurity profiling– Agilent’s LC/MS solutions are globally recognised as the definitive standard. These systems provide the sensitivity and specificity required to detect analytes at levels that were previously unimaginable.

However, the “Chemetrix Edge” lies in how we support this technology. We recognise that method development for LC/MS is a specialised skill. Our support department acts as an extension of your own team, providing on-site assistance to help you develop, optimise, and troubleshoot your pharmaceutical methods. By leveraging our local application expertise, you can reduce the time spent in method development and ensure that your LC/MS system is performing at its peak from day one.

Chemetrix supports this hardware through a comprehensive service programme that goes beyond simple repairs. We offer tailored preventive maintenance and rapid-response technical support to ensure your 1290 Infinity III stays in a qualified state. By integrating our service expertise with this robust hardware, we help labs eliminate the “time traps” of manual intervention. Our goal is to ensure your staff spend less time worrying about baseline
drift and more time focusing on high-value data interpretation.

The reward of proactive support

The transition from a reactive laboratory to a proactive one is transformative. When you partner with a specialist who understands pharmaceutical applications, the results are measured in more than just uptime. You gain the peace of mind that comes from knowing your methods are robust, your instruments are qualified, and your data is defensible.

Our most successful pharmaceutical partners are those who have moved away from viewing instrumentation as a commodity and have embraced it as a collaborative workflow. This partnership leads to faster validation cycles, fewer “Out of Specification” (OOS) investigations, and a laboratory team that is empowered by their technology rather than frustrated by it.

The complexities of testing diverse consumer products

How Agilent’s advanced analytical instruments support comprehensive testing

The growing importance of Food Safety

Food safety is non-negotiable. Defined by the World Health Organization (WHO) as the prevention of hazards – both chronic and acute – that can harm consumer health, it forms the backbone of a trustworthy food supply chain. Hazards may include microbial contamination, pesticide residues, heavy metals, and even naturally occurring toxins, all of which can pose serious risks if left unchecked.

Food quality, while often considered alongside safety, addresses different concerns. It encompasses attributes such as flavour, texture, appearance, and even the origin of a product. While safety ensures a product is fit for consumption, quality determines its value and appeal to consumers.

For food producers, striking a balance between these two aspects is essential to building trust and maintaining competitiveness.

Why Mass Spectrometry?

Mass spectrometry has become a cornerstone of modern food safety testing, thanks to its unparalleled sensitivity, accuracy, and versatility. Unlike traditional methods, which may require separate tests for different contaminants, mass spectrometry can detect and quantify multiple analytes in a single run. This capability significantly enhances efficiency and reduces the time required for analysis – a critical advantage for laboratories handling high sample volumes.

Key Advantages of Mass Spectrometry in Food Safety

Unmatched sensitivity and precision

Mass spectrometry can detect contaminants at trace levels, often in parts per billion (ppb) or even parts per trillion (ppt). This is vital as regulatory agencies worldwide demand more stringent detection limits to protect public health.

Multi-analyte detection

With mass spectrometry, laboratories can analyse multiple contaminants simultaneously, including pesticides, heavy metals, mycotoxins, and allergens. This not only improves throughput but also reduces the cost and complexity of testing.

Simplified sample preparation

Advanced mass spectrometry systems streamline sample preparation, reducing the likelihood of human error while speeding up the testing process.

Adaptability across food matrices

From solid foods like grains and meats to liquids like milk and juices, mass spectrometry can handle diverse food matrices, making it a versatile solution for the food industry.

Transforming Food Safety Testing

One of the most significant developments in mass spectrometry is the rise of inductively coupled plasma mass spectrometry (ICP-MS). Historically viewed as complex and challenging to operate, ICP-MS has undergone a transformation. Modern instruments now feature user-friendly interfaces, automated optimisation, and built-in diagnostic tools, making them accessible to labs of all sizes.

ICP-MS is particularly valuable for detecting heavy metals such as lead, cadmium, and mercury, which can have severe health consequences even at low concentrations. The technique’s sensitivity and specificity ensure that contaminants are accurately identified and quantified, enabling producers to meet regulatory requirements with confidence.

Another breakthrough is the integration of liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). These methods are widely used for detecting pesticide residues and volatile organic compounds in food products. The combination of chromatography and mass spectrometry allows for the separation and precise identification of compounds within complex mixtures, ensuring reliable results.

Addressing the challenges of a globalised food supply chain

In a globalised food economy, the complexity of supply chains adds another layer of risk. Ingredients sourced from diverse regions can introduce contaminants at various stages, making robust testing protocols indispensable. Additionally, the transportation and storage of food products can create opportunities for microbial growth or chemical alterations.

Regulatory bodies worldwide, such as the European Food Safety Authority (EFSA) and the United States Food and Drug Administration (FDA), have responded by tightening standards and lowering acceptable thresholds for contaminants. As a result, food manufacturers must adopt advanced technologies to stay ahead of compliance requirements.

Mass spectrometry provides the tools needed to address these challenges. Offering rapid, reliable testing, enables stakeholders to identify potential issues early in the supply chain. For example, a shipment of imported spices can be tested for pesticide residues before distribution, preventing contaminated products from reaching consumers.

Moreover, mass spectrometry supports traceability – a key component of modern food safety systems. By linking test results to specific batches or production lots, producers can quickly identify and recall affected products in the event of a safety breach. This level of accountability is essential for maintaining consumer trust and avoiding costly disruptions.

Digital labs

This move by Agilent signals that the digital age is very much here for laboratories. Science has always driven the world forward and now it will do the same for laboratories.

The lab of the future is a concept built on the foundation of digitalised labs. It encompasses smart technological workflow systems that are connected and capable of collecting vast amounts of data via integrated automation.

A digitalised lab should be considered a more advanced lab as it has more access to data. With data being key to transforming science, increasing amounts of data generated in any lab, let alone a digitally connected lab, could be a game-changer – but only if it’s collected and synthesised into information and knowledge that is useful.

The digital environment (i.e., paperless work in an electronic format) capitalises on digitalisation. It incorporates all of the necessary instrumentation for complete data analysis and enables the full value of the data for decision-making. The ability to monitor operations and provide more sophisticated insights is a core reason for introducing AI into the operational lab environment.

Transforming science

Artificial intelligence (AI) is often defined as the ability of a machine to learn how to solve cognitive challenges. However, in the context of scientific methodology and laboratory interconnectivity, AI is starting to be used for capturing data to model human observation and decision-making processes.

Accessing this powerful source of information will become a necessary component of scientific productivity. This is an inevitable next step in creating lab management systems that are so efficient and provide knowledge that is so valuable that only AI will be able to produce them.

AI, coupled with universal sensing capabilities to detect and monitor a range of variables, e.g., an instrument’s power draw, enables companies to realise certain operational and financial benefits to their business and plan for the future. Through high-quality and readily available insights, AI enables the simultaneous monitoring of all equipment usage in the lab and holistic capacity tracking.

Staying competitive in a competitive world

Globally, scientific innovation is accelerating, so labs need to consider the technology investments required to become digitally enabled in order to keep up and stay competitive. We live in a data-driven world, so scientific laboratories must fundamentally transform how they create, manage, and effectively use all the data that is generated in their lab ecosystem. Achieving and sustaining a competitive edge in a world of constant change will require the continual transformation of lab operations and scientific data management. This will be the first and most important step toward becoming a truly digitalised lab.

Standardising honey fingerprinting methods

Although previous work has been done developing case studies for fingerprinting foodstuffs, including honey, the approaches among laboratories have been different regarding sample preparation and instrumental conditions. There are also differences in terms of data processing and analysis. As a result, two laboratories analysing the same sample may obtain slightly different results. Ideally, developing a standardised fingerprinting method that could be used across all LC/MS-based workflows, enabling the same testing technique to be used across multiple laboratories, would be optimal and where future work is aimed.

Read our article on Fingerprinting Honey to Ensure Purity

When addressing the issues of food safety, product quality, and authenticity, each may be governed by separate sets of regulations. For example, looking at the residues of contaminants in honey, such as pesticides, there may be differences globally. Countries may have their restrictions for the maximum limit for specific compounds. Contaminants are a part of the picture when considering fingerprinting for honey, but permitted levels may vary between countries.

Additionally, as samples come from the field to the lab for testing, there is potential interest in reversing this and bringing the lab out into the field instead. This interesting but not yet recognised capability would enable regulators and the global food industry to respond more quickly to honey contamination and food fraud.
