Speciation Studies of Metal Ions in Environmental and Biological Media Using Supported Liquid Membrane Extraction (pdf)

LCGC International sat down with Jose Bernal to discuss his latest research in using pyrolysis gas chromatography–mass spectrometry (Py-GC–MS) and other chromatographic techniques in studying microplastics in food analysis.

In this column, we discuss the label-free and stable isotope labeling proteomics approaches that help in biomarker discovery. We also discuss the different enrichment techniques, such as stable isotope labeling by amino acid in cell culture (SILAC), isobaric tags for relative and absolute quantitation (iTRAQ), and tandem mass tags (TMT, that help in measuring low-abundance protein biomarkers.

This article describes the current highlights of using molecular imprinted polymers (MIPs) in sample preparation.

Ronald Piervincenzi, chief executive officer of the United States Pharmacoepia, focused on how collaboration and component quality can improve worldwide pharmaceutical production standards during a lecture at the Eastern Analytical Symposium (EAS) last month.

Messina Institute of Technology scientists used gas chromatography–mass spectrometry (GC–MS) to profile illegal samples of Cannabis sativa L.

Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.
