A hybrid HILIC–ion exchange column was used for the analysis of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) compounds in environmental waters. This direct injection LC–MS method enables simultaneous measurement of ultrashort- chain, alternative, and legacy PFAS in potable and non-potable waters.

Abuse of synthetic opioid prescription painkillers such as fentanyl, along with a rapidly growing list of illicit analogues, is a significant public health problem. In this study, we developed a simple dilute-and-shoot method that provides a fast 3.5-min analysis of fentanyl and related compounds (norfentanyl, acetyl fentanyl, alfentanil, butyryl fentanyl, carfentanil, remifentanil, and sufentanil) in human urine by liquid chromatography–tandem mass spectrometry (LC–MS/ MS) using a Raptor Biphenyl column.
