A gas chromatograph having a column which separates respective components contained in a gas sample introduced via a carrier gas over time, wherein an analysis mode and a standby mode can be switched and executed. The gas chromatograph apparatus comprises: a carrier gas flow path, a column protection gas
网页2012/02/02 · Also disclosed are column assemblies for gas chromatography, wherein at least a portion of the tube of the column assemblies is formed into an arcuate shape. In one aspect, at least a portion of the tube is formed into a loop shape. It is contemplated that the loop shape has an inner diameter of between about 1 inch and about 12 inches.
网页2019/08/30 · Gas chromatography is a method that utilizes a gaseous mobile phase and a solid stationary phase. The sample is vaporized and passes through the coiled column that separates the components. These molecules can be detected using various spectroscopic equipment, which is very useful in identifying and quantifying components in a sample.
