GC-MS Insights

What is GC-MS?

GC-MS stands for Gas Chromatography-Mass Spectrometry. It is an analytical technique that combines the features of gas chromatography and mass spectrometry to identify different substances within a test sample. Gas chromatography separates the components of a mixture, and mass spectrometry identifies each of those components based on their mass-to-charge ratio. It is commonly used in environmental monitoring, food safety, pharmaceuticals, and forensic science to detect and quantify volatile and semi-volatile organic compounds.

GC-MS Competitor Technologies

LC-MS

LC-MS is a competitor because it achieves similar analytical goals as GC-MS but is used for different types of samples (e.g., larger, more polar, or thermally labile molecules that are not amenable to GC).
