GC–MS has been regarded as a "gold standard" for forensic substance identification because it is used to perform a 100% specific test, which positively identifies the
Spectroscopy 101 – Types of Spectra and Spectroscopy What can we learn from different types of spectra? The basic premise of spectroscopy is that
Learn about the fundamentals of gas chromatography (GC). This overview explains the basic principles of gas chromatography and the key components of a gas
What is Gas Chromatography/ Mass Spectrometry? Gas chromatography/mass spectrometry (GC/MS) combines two analytical tools to identify and measure the
GC-MS is a hybrid analytical technique that combines the separation power of gas chromatography with the molecular identification capability of mass spectrometry.
Mass Spectrometry is an analytical technique that forms ions from atoms or molecules and measures their mass-to-range (m/z) ratios in gas phase. Mass Spectrometry can provide information about
Mass spectrometers are used to analyze gases. Solid or liquid substances can also be analyzed if they are vaporized in an upstream inlet system. The gas is diluted
Archer J.P. Martin (Figure 3 1 1 ) and Anthony T. James (Figure 3 1 2 ) introduced liquid-gas partition chromatography in 1950 at the meeting of the Biochemical
If a molecule can be converted into a gas phase ion it can be interrogated by this technique. Making possible the study of proteins by mass spectrometry required the development of methods to convert
The gas chromatograph separates the components of a mixture in time, and the mass spectrometer provides information that aids in the structural identification of each component.” — Gas
