PFAS analysis requires special conditions, including sample preparation, such as the absence of PFAS blank values in all materials and equipment used. The spectrum of analytes in the PFAS field is constantly expanding, and the focus is increasingly on long-chain PFAS. The X-TRACTION® PFAS, in which all materials within the fluidic path have been replaced by PTFE-free components, is ideally suited for this purpose!
Extraction with the X-TRACTION® PFAS s carried out according to the Pressurised Fluid Extraction (PFE) principle. With this principle, in-house tests have shown that long-chain PFAS or neutral sulphonamides can be recovered better than with conventional extraction methods, such as shaking out. On the LCTech website you can see a comparison diagram of both extraction methods of doped soil matrix.
