A highly selective dispersive liquid-liquid microextraction approach based on the unique fluorous affinity for the extraction and detection of per- and polyfluoroalkyl substances coupled with high performance liquid chromatography tandem-mass spectrometry.
Juan Wang,Yali Shi,Yaqi Cai +2 more
TL;DR: This highly fluoroselective DLLME technique can greatly decrease the matrix effect that occurs in mass spectrometry detection when applied to the analysis of urine samples, confirming that the developed D LLME technique is a promising method for the extraction of PFASs in real samples.
