Gas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.
Supelco provides high quality derivatization reagents for acylation.Acylation, an alternative to silylation, allows the conversion of compounds with active hydrogen such as -OH, -SH, and -NH into esters, thioesters and amines, respectively. A very popular example of this method is the insertion of perfluoracyl groups to enable electron capture detection (ECD). Carbonyl groups adjacent to halogenated carbons enhance the ECD res…
Supelco provides high quality derivatization reagents for akylation and esterification.Alkylation is the replacement of the active hydrogen in R-COOH, R-OH, R-SH, R-NH, R-NH2, R-CONH2, R-CONH-R′ with an alkyl group, or sometimes an aryl group.Esterification is the first choice for derivatization of carboxylic acids and other acidic functional groups. Acids are reactive compounds, and are too polar to be well separated by gas c…

Specialty In-Line Purifier for GC-MS HeliumThe most sensitive GC-MS instruments require a steady stream of ultra-high purity (99.99999%) helium for optimal performance. To achieve this level, a specialty purifier is required. These purifiers contain multiple adsorbent beds for the removal of all critical contaminants. Additionally, the adsorbent materials are packed into the cartridge under helium to ensure no other gas off-g…
Cyclodextrin-based DEX and Astec CHIRALDEX phases are stable, high boiling liquids and make effective CSPs for enantiomer separations by GC. The two lines exhibit complementary selectivity.Cyclodextrins are macromolecules composed of 6 or more D(+)-glucose residues bonded through α-glycosidic linkages. They are classified according to the number of glucose residues they contain: α-cyclodextrins (six residues), β-cyclodextrins…
ChromSquare GC/GC is data analysis software for comprehensive gas chromatography (GC/GC). GC/GC analysis uses two different types of columns for higher resolution. This makes it possible to analyze samples with a large number of components that are difficult to identify using regular GC or GC/MS systems, due to overlapping peaks. ChromSquare software enables qualitative and quantitative analysis in a single window. Moreover,…
