The challenges of ultra-short chain PFAS
Ultra-short-chain PFASs (perfluoroalkylated and polyfluoroalkylated substances) represent a major challenge for analytical laboratories. Their unique properties, such as their low molecular weight and high polarity, make it difficult to incorporate them into standard chromatographic methods. Yet their analysis is crucial to understanding their environmental and health impact, particularly because of their persistence and bioaccumulation.
To meet the needs of researchers, Wellington now offers an extended range of certified reference standards dedicated to these specific compounds. These products include ultra-short-chain perfluoroalkyl acids (PFCAs) and perfluoroalkanesulphonates (PFSAs), 2 categories that are particularly difficult to detect accurately. In addition, each standard was rigorously characterised using an analytical method specially developed for these unique analytes.
Why are these standards essential for your analyses?
Ultra-short-chain PFASs have high volatility and solubility, which can lead to inaccurate results with traditional methods. Wellington Laboratories’ certified standards guarantee not only greater accuracy in detection, but also the standardisation essential for reliable comparisons between laboratories.
In addition, these standards overcome the analytical challenges associated with poor chromatographic separation, reducing the risk of interference and improving the reproducibility of results.
Tools for analysis laboratories
Thanks to these new reagents, laboratories specialising in chromatography and mass spectrometry can broaden their field of investigation. These solutions offer greater flexibility in adapting their methods to meet increasingly stringent regulations on PFAS, while improving understanding of the risks associated with these substances.
