Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [ 1 ]
Erika Cremer (20 May 1900, Munich – 21 September 1996, Innsbruck) was a German physical chemist and Professor Emeritus at the University of Innsbruck [1] who is regarded as one of the most important pioneers in gas chromatography, [1] as she second conceived the technique in 1944, [1] after Richard Synge and Archer J.P. Martin in 1941.
The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same. Most commonly, the FID is attached to a gas chromatography system. The eluent exits the gas chromatography column (A) and enters the FID detector’s oven (B). The oven is needed to make sure that as soon as the eluent exits ...
NICI AG, a German toy manufacturer Negative ion Chemical ionization , now more frequently abbreviated NCI, a mode of operation of a gas chromatography - mass spectrometry (GC-MS) system that allows molecules resolved by GC to be measured as negative ions by MS.

Unresolved complex mixture (UCM), or hump, is a feature frequently observed in gas chromatographic (GC) data of crude oils and extracts from organisms exposed to oil. [1] The reason for the UCM hump appearance is that GC cannot resolve and identify a significant part of the hydrocarbons in crude oils. The resolved components appear as peaks ...
The first on-line coupling of gas chromatography to a mass spectrometer was reported in the late 1950s. [4] [5] An interest in coupling the methods had been suggested as early as December 1954, [6] but conventional recording techniques had too poor temporal resolution.
A DID is an ion detector which uses a high-voltage electric discharge to produce ions.The detector uses an electrical discharge in helium to generate high energy UV photons and metastable helium which ionizes all compounds except helium. [1]
