Tandem liquid chromatography - mass spectrometry ( LC/MS/MS ) has high selectivity and sensitivity and is therefore the most commonly used analytical method for determining the content of perfluoroalkyl surfactants in biological and environmental samples. Performing a solid phase extraction ( SPE ) procedure prior to liquid chromatography - mass spectrometry / mass spectrometry ( LC/MS/MS ) analysis is one of the most common methods for extracting perfluoroalkyl surfactants from aqueous environmental matrices. In this study, we developed an LC/MS/MS direct injection method that showed that this simple LC/MS/MS workflow provides excellent analysis of drinking water and surface water perfluoroalkyl surfactants. Sensitivity and specificity.
