2023年4月19日 · Gas chromatography mass spectrometry (GC-MS) is an analytical technique that combines two powerful techniques; gas chromatography and mass spectrometry and is used to separate, identify, and quantify volatile compounds. It is therefore perfect for analyzing the many relatively low molecular weight compounds.

2024年2月16日 · 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.

This GCMS primer explains the fundamentals of gas chromatography mass spectrometry, and provides the basics of GC/MS theory and technique for the gas chromatograph (GC) and the mass spectrometer (MS) with ion source, quadrupole mass analyzer, and detector.

Discover the differences between GC, GC-MS, and GC-HS techniques, their applications, and the importance of high-purity solvents for accurate analytical results.

2023年2月12日 · What is Gas Chromatography-Mass Spectrometry (GC-MS)? GC-MS is the separation technique of choice for smaller volatile and semi-volatile organic molecules such as hydrocarbons, alcohols, and aromatics, as well as pesticides, steroids, fatty acids, and hormones.

In 1955-56, Dow Chemical scientists Fred McLafferty and Roland Gohlke first demonstrated the combination of gas chromatography (GC) and mass spectrometry (MS) to identify individual substances in a mixture.

Gas Chromatography-Mass Spectrometry (GCMS) is a highly significant analytical technique in modern chemistry that combines two powerful analytical methods, gas chromatography and mass spectrometry, to detect and identify various organic compounds in complex mixtures.

Gas chromatography combined with a triple quadrupole mass spectrometry system is referred to as GC-MS/MS. The triple quadrupole MS provides a higher level of selectivity and is best suited to analyses where the highest sensitivity is required.

By analysing mass-to-charge (m/z) ratios, our experienced analysts can accurately confirm compound identity, differentiate isomers, and quantify trace substances, making GC-MS/MS a powerful tool in forensic, environmental, and pharmaceutical applications.

GC-MS is often used to qualitatively and quantitatively determine organic compound purity and stability and to identify components in a mixture. GC-MS is commonly used in many disparate fields, including environmental chemistry for atmospheric, soil, and water research; forensic
