A01- GC9800 Gas Chromatography

Descriptions

GC9800 series gas chromatography is a kind of practical analytical instrument with high Performance which allows assembly of highly sensitive thermal conductivity detector (TCD) or highly stable hydrogen flame ionization detector (FID). The design and fabrication of this instrument are based on the principle of gas chromatography. It has reasonable structure, high sensitivity, and it is easy for operation and maintenance.

When operating GC9800, a certain kind of carrier gas (H2, N2, or Ar, which is called mobile phase) is needed. And the stationary phase is filled in the chromatographic column. The compositions of analyzed mixture are separated by multiple distributions between two phases or because of the difference of bulk additive adsorbability they are separated to different compositions. The single composition after chromatographic fractionation enters detector along with the carrier gas one after another. Then the corresponding electric signals will appear in the detector and be recorded with chromatographic data processor or chromatographic working station. Thus qualitative or quantitative analysis can be carried to each composition in mixture.

The instrument can be equipped with different sampling devices and it can be used to analyze gas, liquid and solid samples. In addition, GC9800 can make macro-analysis and micro-analysis for various gases and organic mixtures whose boiling point is below 350ºC. GC9800 is an indispensable analytical instrument in

the fields of petroleum, chemical industry, spice, medicine, hygiene, metallurgy, electric power, gas industry and many specific domains.
