GC-MS – News and Features

Gas chromatography mass spectrometry (GC-MS) is an important technique in the analytical chemist's armory. In this article we explore how GC-MS and GC-MS/MS work, what they can tell us, their strengths, weaknesses and applications.

Scientists have developed a new authentication tool to check the geographical origin of virgin olive oil as a control on quality and to detect adulteration and fraud.

Cannabis scientists made an odorous breakthrough last year. A group of researchers finally identified 3-methyl-2-butene-1-thiol as the root cause of the signature skunky smell of hemp and cannabis. Now a new paper details the method.

We spoke to Geoff Winkett and Michel van den Berge from Agilent, about the issues posed by microplastics analyses and how molecular spectroscopy is rising to the challenge.

An analysis of more than 200 grape and wine samples has provided guidelines for using analytical chemistry to identify wines that have been affected by smoke from wildfires.

Scientists have come up with a naturally derived wild strawberry aroma by having an edible fungus make it from blackcurrant juice production waste.

In this article, we explore py-GC-MS, how it can be used in the field of microplastic analysis and the advantages it may offer over traditional methods based on microscopy or spectroscopy.

Researchers have successfully developed plants that can be used to detect organic pollutants, such as polychlorinated biphenyls and endocrine-disrupting chemicals, which contaminate soil and water.

This article highlights the adverse impact of microplastics (MPs) on our environment, detection methods for MPs and the challenges in the detection of MPs.

For home gardeners and farmers, herbivorous insects present a major threat to their crop yields. Researchers now report they have developed a way to bottle the “smell of fear” produced by predators to repel and disrupt destructive insects naturally without harsh substances.
