Analysis of PFAS in Fish Tissue Using SFE and LC-MS/MS


In this study, supercritical fluid extraction (SFE) was evaluated as an alternative sample preparation technique for the extraction of eighteen PFAS compounds from fish tissue, as a preconcentration step prior to their analysis by LC-MS/MS. Using the Shimadzu Nexera UC offline SFE system, the results were excellent for recovery, linearity and reproducibility.

LC/MS/MS Method Package for Restricted Chemicals in Textiles


In recent years, countries throughout the world have been considering the regulation and investigating hazardous chemicals in textiles.  This method package provides analysis methods covering the major restricted chemical compounds.

Regarding perfluoro compounds, this targets PFOA and PFOS included in the regulations, as well as their related salts and other perfluoro compounds which are not currently included in the regulations.
