Gas Chromatography–Mass Spectrometry (GC MS) News and Research

RSS

GC-MS involves coupling a mass spectrometer to a gas chromatography column. Based on the properties of the sample, different compounds of the sample elute at different times based on the retention time. The mass spectrometer then captures and ionizes different particles, and further detects them based on their mass-to-charge ratio.

Preventing gas chromatography (GC) leaks

Leaks at gas chromatography (GC) column connections are a common source of frustration and wasted time in laboratories. Time is often spent manually tightening connections between columns using a handheld tool – time which could otherwise be spent analyzing results or running more investigations. Preventing GC leaks has become a priority for researchers looking to save time and money while achieving high quality results.
