As the demand for extensive PFAS monitoring in drinking water and environmental water (non-drinking water) increases, efficient analytical methods are required. In this study, we developed a simultaneous analysis method targeting alternative (short-chain) and conventional (long-chain) PFAS, as well as ultra-short-chain PFAS, including C2 (ultra-short-chain), C3, C4, C6, C8, and alternative compounds. Below, we report the results of the experiments. For questions or more information about PFAS analysis, please contact us.

The analysis of low-concentration per- and polyfluoroalkyl substances (PFAS) requires high sensitivity and low background levels throughout the entire workflow, from sample collection, transportation, and storage to analytical instrumentation and sample pretreatment. Restek's solid-phase extraction column, the Resprep Polymer WAX SPE cartridge, enables accurate quantification of low-concentration PFAS compounds in drinking water while meeting the requirements of EPA Method 533.

A rapid and simple LC-MS/MS method for comprehensive PFAS analysis has been established. It is now possible to consistently analyze ultra-short-chain (C2 and C3), short-chain (C4 to C6), and alternative PFAS, as well as long-chain PFAS (C8 and above). Compounds containing trifluoroacetic acid (TFA), which are difficult to retain with conventional methods, can be reliably retained and analyzed using the Raptor Polar X column. If you are experiencing issues with weak retention on reverse phase columns or other columns that exhibit strong ion exchange mechanisms, leading to overly strong retention or poor peak shapes, please take a look at this. https://www.restek.com/global/ja/articles/japanese-novel-stationary-phase-for-comprehensive-pfas-analysis-ultrashort-chain-c2-c3-alternative-and-legacy-compounds For questions or more detailed information about PFAS analysis, please feel free to contact us.
