Next-Level PFAS Screening and Identification Using Trapped Ion Mobility Spectrometry (TIMS)

Patrick Lavery is an Editor for the MJH Life Sciences brands LCGC and Spectroscopy, and their respective websites, 

. He previously spent nearly a decade as a news anchor, reporter, and producer at New Jersey 101.5 FM.

This report not only focused on the different types of portable X-ray fluorescence (pXRF) spectrometers available, but also their capacities for limits of detection and quantification (LOD and LOQ, respectively), linearity, and calibration strategies.

Review of Portable X-ray Fluorescence in Analysis Applications for Solid and Liquid Food Samples

 is a principal scientist at Syft Technologies in New Zealand. He joined Syft in late 2002 after completing his Ph.D. in physical chemistry at the University of Canterbury, and postdoctoral fellowships at the Universities of Geneva, Western Australia, and Canterbury. He has over 30 peer-reviewed publications on a wide range of SIFT-MS applications, and has contributed numerous conference papers. Direct correspondence: 

 is a senior applications chemist and SIFT-MS expert at Element Materials Technology (formerly Anatune), based in Cambridge, United Kingdom. Mark graduated from the University of Southampton, UK, with a Ph.D. in electrochemistry. He was with the Malaysian Rubber Board’s UK research centre for 12 years, first as a senior analyst, then as head of the analytical section. He joined Element in early 2015 in a role that supports and expands the analytical capability of SIFT-MS—with a particular focus on autosampler integration and the development of automated test methods.
