Abstract:
LC-MS/MS is firmly established as a key analytical technique used to assess the prevalence of PFAS in natural and human environments. The analysis is challenging, due to the low detection limits required, while their ubiquitous use in many materials means that special instrumental considerations are required to prevent background interference. This webinar discusses some of the key considerations when developing LC-MS PFAS methods, including use of a delay column, sample preparation approaches and sample injection considerations. Finally, a series of example PFAS applications are discussed.
