This application note outlines a simple SPE procedure for the extraction of 26 diverse per- and polyfluoroalkyl substances (PFASs) in drinking water using UCT’s polymeric weak-anion exchange SPE cartridges (ENVIRO-CLEAN® WAX). Instrumental analysis was carried out by LC-MS/MS in less than 10 minutes using a Selectra® C18 HPLC column. Overall, excellent recovery and reproducibility were obtained at the low concentrations tested.

Synthetic opioid drugs, such as fentanyl and sufentanil, have very high analgesic potency. Abuse of these prescription painkillers—along with a rapidly growing list of illicit analogues—is a significant public health problem. In this study, we developed a simple dilute-andshoot method that provides a fast 3.5 minute analysis of fentanyl and related compounds (norfentanyl, acetyl fentanyl, alfentanil, butyryl fentanyl, carfentanil, remifentanil, and sufentanil) in human urine by LC-MS/MS using a Raptor Biphenyl column.
