Conclusion
PFAS are a group of environmental contaminants which are of increasing concern in many countries. PFAS can be difficult to analyse due to the number of potential 'targets', which often exist in isotopic mixtures or groups of related compounds and which can exhibit different physical behaviour and interactions in the environment. Since PFAS are commonly used in the manufacture of consumer products and laboratory supplies, it is necessary to eliminate any potential sources of contamination during sample collection, transport, preparation, and analysis High quality analysis of PFAS contaminants therefore depends on laboratories having access to reliable and robust testing methodologies. LGC AXIO provides solutions to to support the quality control activities of laboratories undertaking work in this field. Through our range Dr Ehrenstorfer reference materials labs can use fully characterised, including isotopic composition, reference standards during method development, for spike recovery and as routine analytical calibrants. In addition, LGC AXIO supports laboratories by providing proficiency testing samples for the determination of PFAS in an environmental matrix, through the AQUACHECK scheme. Proficiency Testing is a independent assessment of a laboratories competence, testing the entire process from sample receipt to reporting of results and supporting the whole system of quality control.
