LCGC North America
John Dolan discusses the causes of peak tailing, how to measure it, preventive measures, and why newer column types are less prone to tailing problems.
Analysis of Ultrashort-Chain and Short-Chain (C1 to C4) PFAS in Water Samples (May 2025)
May 15th 2025In this study, an accurate, reliable analytical LC-MS/MS method for PFAS in water was developed to specifically quantify C1 to C4 PFAS in both potable and non-potable sources. A direct injection workflow was implemented to simplify the testing process and to avoid potential contamination originating from poor sample preparation procedures.
