A generalized approach using DoE is presented for the optimization of DHS extraction parameters.

Rudolf Krska and Michael Sulyok from the University of Natural Resources and Life Science in Vienna, Austria, discuss their recent work developing a multi‑analyte approach using liquid chromatography tandem mass spectrometry (LC–MS/MS), and the issues surrounding agrocontaminants in animal feeds.

There are some problems with LC separations that will probably never go away, such as shifting retention times.

With the greater sensitivity, resolution, and advanced data handling capabilities now available comes a new set of experimental uncertainties.

Our annual review of new liquid chromatography columns and accessories introduced recently.
