Mass spectrometry is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-ch

Gas chromatography–mass spectrometry is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications

…temperature. The sample can be prepared by an earlier analyzer. For example, it can simply be the gaseous output of a gas chromatography machine as in GC-MS, or the liquid output of a high-performance liquid chromatography machine, as in HPLC-MS. The recently developed "atmospheric pressure ionization…
