Verification and analysis of PFAS in industrial and environmental samples

PFAS analytics for the best results

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals used in numerous products due to their water, grease and dirt-repelling characteristics. Their release entails serious health and environmental risks, which is why governmental and standardisation forums are working on measures to counter the most harmful PFAS. For this reason, the exact monitoring of PFAS in industry is to be strongly recommended.

Our accredited laboratory uses the latest technology and sound expertise to ensure the precise and comprehensive analyses of your samples, so that you can be certain your processes and products meet regulatory and ecological standards. We acquire the total concentration of organic fluorine compounds in your sample by determining the sum parameters AOF, EOF and TOF to make an effective risk assessment possible.

PFAS analytics in the laboratory at Quality Analysis - your advantages

At Quality Analysis we determine the overall levels in your sample by means of the sum parameters AOF, EOF and TOF. These sum parameters permit the measurement of all organic compounds containing fluorine in a sample. They provide a more precise estimation of the PFAS content than analysis of the individual compounds and ensure your products comply with verification limits. Due to the numerous unknown PFAS compounds, single-substance analysis cannot provide an accurate estimate of the risk potential. Sum parameters, on the other hand, provide valuable information about the spatial distribution and concentration of PFAS in your sample. The approach is not only more precise, it is also less expensive and saves time because it provides a broader overview of the fluorine levels without the need to analyse each individual compound specifically.

We verify the presence of per- and polyfluoroalkyl substances using combustion ion chromatography (CIC) in a variety of matrices such as water, soils, plastics and biological samples. We determine the sum of organically bound fluorine (AOF, EOF, TOF). These results give you more information and permit better categorisation of the risk.

Challenges of PFAS analytics

During PFAS analytics, it is necessary to take into account, on the one hand, the diversity of more than 10,000 different compounds and the often low concentrations of these chemicals in different environments. On the other hand, the characteristics of PFAS can vary depending on the matrix, which affects the accuracy of the analysis. As a consequence, it is difficult and time-consuming to determine the exact structures and concentrations of all these compounds in samples. Against this background, sum parameter methods are of major importance because they offer a comprehensive overview of the PFAS levels - without the need to specify every single compound. They are therefore essential for an effective risk assessment and for compliance with verification limits.

Our experts combine sound expertise with modern technology for PFAS analytics to deliver exact, dependable results. We make sure you can rely on our analyses to verify that your products meet safety and environmental standards.

Frequently asked questions about PFAS Analytics

Why is PFAS analytics necessary?

PFAS (per- and polyfluoroalkyl substances) are found in many industrial and consumer products. Their durability and longevity, however, lead to accumulation in the environment and in living organisms, which has resulted in growing regulatory requirements and bans. The analysis of PFAS is therefore imperative to ensure compliance with these statutory regulations and to monitor the proliferation and concentration of these chemicals.

What are per- and polyfluoroalkyl compounds?

PFAS are industrially manufactured organic compounds in which the hydrogen atoms bound to the carbon are completely (perfluorinated) or partially (polyfluorinated) replaced by fluorine atoms. Due to this structure, PFAS have special chemical and physical characteristics. They are, for instance, water and oil-repellent and therefore particularly useful in industrial applications. They are also very stable, which in turn results in their high persistence, that means they are difficult to break down and are, in the meantime, omnipresent in the environment and living organisms. For this reason they are also termed "forever chemicals".

Where are PFAS analytics used?

They are used in many areas, including environmental monitoring, foodstuff and water quality tests, product inspection and industrial quality assurance. In environmental and water management, PFAS analytics play a key role because they help to monitor and secure the quality of water resources. This is particularly relevant during the analysis of drinking water and surface water for PFAS contamination. In the plastics industry, these analytics are used to ensure the safety of plastic products, in particular products that are in direct contact with foodstuffs or the skin. Furthermore, during the evaluation of soil samples PFAS analytics permits precise assessment of soil quality, above all in regions potentially affected by industrial pollution. These analyses are crucial for ensuring compliance with environmental standards and designing production processes so they are sustainable.

Why is the determination of the sum parameter better suited to the measurement of PFAS than individual analytics?

The substance group PFAS includes many thousands of individual substances, up to now de minimis thresholds have only been introduced for a few – there is therefore no evaluation framework available for many compounds. Also, for many applications it is still unknown which PFAS are used and which transformation and decomposition products are produced. It would therefore be necessary to test a sample for tens of thousands of individual compounds to obtain informative results by means of individual substance analytics. One can imagine: this testing would not only be time-consuming, it would also involve very high costs. Sum parameters, on the other hand, offer an efficient means of obtaining a comprehensive picture of PFAS levels, which is particularly advantageous in industrial applications.
