There is a need for fast and reliable PFAS analyses to monitor drinking water quality. We report on the use of semi-automated sample preparation with EPA methods 533 and 537.1, assessing performance and processing time.
Three-dimensional (3D) printing shows promise for creating stationary phases
with tailored geometries. We present a method that overcomes limitations of
other approaches, and can produce columns with a feature resolution of 10 μm.
Improved analysis of pharmaceutical and natural medicine products requires advances in reversed-phase LC stationary phases. We examine two synthesized stationary phases with applicability in quality control and chiral separation for analysis of natural products.
