Per- and polyfluoroalkyl substances (PFAS) in surface water have become a major concern due to their persistency and toxicity. We recently spoke to Stefan Van Leeuwen and Bjorn Berendsen of Wageningen Food Safety Research (WFSR), in The Netherlands, about their novel research into non-targeted PFAS screening using an LC–HRMS method with fragment ion flagging.

Modern ion mobility–mass spectrometry (IM–MS) is a key separation technology for detailed molecular characterization studies and also as part of emerging data acquisition strategies for demanding small molecule and several applications. Here is what you need to know.

We explore the impact of two different stationary phases and ion-pair reagents on the retention behavior of a therapeutic peptide using reversed-phase liquid chromatography. This information is of fundamental importance for the development of reliable, selective, and fast analytical methods able to separate and identify the target peptide.

The stochastic theory of chromatography allows one to connect mathematics to separation science in an intelligible form. We take a “walk” through the column at the level of an Ant-Man, where we can see that chromatography is mathematics and mathematics is chromatography!
