Minimize Background. Protect Sample Integrity.
The analysis of per- and polyfluoroalkyl substances (PFAS) requires careful attention to every component of the analytical workflow. At trace-level concentrations, laboratory consumables can become potential sources of background contamination, making material selection an important consideration in PFAS sample preparation and analysis. Fluoropolymer materials such as PTFE are widely used in laboratory products because of their excellent chemical resistance. However, because PTFE contains fluorinated materials, laboratories performing PFAS analysis often select alternative materials for vials, closures, and other sample-contact components to help minimize potential sources of PFAS contamination.

Supporting LC/MS/MS PFAS Workflows
Liquid chromatography-tandem mass spectrometry (LC/MS/MS) is widely used for the analysis of PFAS, particularly for ionic compounds such as perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkyl sulfonic acids (PFSAs). Selecting appropriate sample-contact materials is an important part of maintaining sample integrity throughout the analytical process.
