Using the SHIMSEN Styra SPE column, two effective and complete sample preparation methods for the analysis of PFAS in water have been established.
The methods are applicable to ultrapure water and wastewater, with detection limits as low as 1 ng/L and 10 ng/L, respectively.
Introduction
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have become a global concern due to their persistence, bioaccumulation, and endocrine toxicity. PFAS are discharged into the environment through wastewater treatment plants and then enter water sources through material migration or transformation, leading to the contamination of drinking water. Over 4,000 types of PFAS have been reported, and these substances have significant polarity differences. Therefore, if we need to monitor the contamination of PFAS in water, a complete and accurate sample preparation and instrumental analysis method is crucial. In this application, we referred to the methods in ISO 21675-2019 and EPA 1633, used Shimadzu SHIMSEN Styra WAX and SHIMSEN Styra WAX/GCB columns to enrich PFAS in water, Shim-pack Scepter C18-120 column for separation, and Shimadzu LCMS-8060RX for analysis, and established two effective and complete methods for determining the content of 30 types of PFAS in water.
