Combining silicon micro-nanofabrication technology to create perfectly ordered separation beds on a silicon chip, i.e. micro-pillar array columns (µPACs) is a powerful innovation in liquid chromatography. This article discusses the numerous possibilities of micro-nanofabrication in the future of analytical chemistry in life science, covering sample preparation, separation science, and detection technologies.

The article discusses advancements in two-dimensional liquid and gas chromatography (LC×LC and GC×GC) to address the challenges of analyzing complex samples in non-target analysis.

Dairy milk is one commodity that can be impacted by environmental contaminants, such as PFAS, so it is important to implement extensive, robust, and accurate testing. In this work, a sensitive and reliable method was developed for the analysis of PFAS in milk by LC-MS/MS at levels as low as 0.01 µg/kg.

The following PFAS method collection, organized by region, provides an overview of the scope of current PFAS testing methods and guidelines as well as the recommended products used for each.
