Introduction of an analysis method for PFOS alternative organic fluorine compounds using LCMS.
Perfluorinated compounds (PFCs) have been widely used in applications such as surfactants, surface treatment agents, and water repellents. However, due to their persistence and toxicity to living organisms, as well as their difficulty in degradation in the environment, they are regulated under the Stockholm Convention (POPs Treaty). Research is being conducted on alternative substances to long-chain alkyl PFCs, represented by PFOS and PFOA. Investigations are being carried out on the physical properties and actual conditions of PFCs with lower biological persistence, including short-chain alkyls, alkyl ethers, and cyclic structures. In this study, we introduce the results of establishing an analytical method using LC/MS and investigating a pretreatment method for environmental water samples, using a PFOS alternative substance with distinctive structural features as a model substance. *For more details, please refer to the PDF document or feel free to contact us.*
