To achieve the best selectivity and recovery in liquid–liquid extraction (LLE), a few fundamentals need to be clearly understood.
Pyrolysis–gas chromatography–mass spectrometry has advantages for the analysis of environmental microplastic samples compared to other leading analytical methods, including spectroscopic techniques.
Trace-level pesticides and environmental pollutants in the food supply continue to be a worldwide concern. Here we present a fast-screening workflow for residual pesticides present on the surface of fruits using a GC–MS system with direct heating technology and MS spectral deconvolution.
Highlights of the new high-performance liquid chromatography, mass spectrometry, and chromatography data systems introduced over the past year.
We present our annual review of new products in gas chromatography, introduced between spring 2020 and spring 2021.
Dispersion of analyte zones outside of the column often compromises the quality of an LC separation—particularly in smaller columns with smaller particles. We explain basic concepts in extra-column dispersion from the point of view of an entire instrument.

In the first of the series, Mariosimone Zoccali, discusses the development
of a powerful analytical method to analyze important bioactive molecules using online SFE–SFC–QqQ-MS.
Incognito considers the future of laboratory training, questions the quality of current practices, and assesses the “easy wins” that can be learned across industries.
Elmar Piel’s pioneering work was pivotal to the development of modern-day high performance liquid chromatography (HPLC).
