GS-2010H Universal High Purity Gas Chromatograph

GS-2010H gas chromatograph is a chromatograph developed on the basis of GS-2010III to detect high-purity gas, whichuses a pulsed discharge helium ionization detector (PDHID detector). The PDHID detector is a general-purpose non-destructive detector with extremely high sensitivity. It is a non-radioactive detector. Both inorganic and organic compounds have a high response except Neon, which is especially suitable for the analysis of permanent gases. It is the only detector that can detect to the ng/g (ppb) level. The GS-2010H high-purity gas analyzer developed by our company uses high-purity helium as the carrier gas, and adopts heart-cutting technology, multi-column technology and valve switching technology, which can fully realize the detection of high-purity gas (Such as high-purity hydrogen, high-purity helium,High purity oxygen, high purity nitrogen, High-purity argon, high-purity carbon dioxide), analysis of trace impurities.

Main features of the instrument:
The pulsed helium ionization detector (PDHID) of VICI (Valco) is used. 
The selected injection/switching valves are imported purge type products.
All sample flow paths are internally polished or passivated 316L stainless steel tubing to avoid analysis errors caused by adsorption and desorption on the inner wall of the tubing.
Select specially treated molecular sieve packing to avoid analysis errors caused by abnormal adsorption of oxygen and carbon monoxide.
The instrument uses a back pressure valve to boost the sampling method, which can not only reduce the fluctuation of the sampling signal, but also improve the repeatability and sensitivity of the analysis to a certain extent.
lCarrier gas and sample gas are equipped with 2um aperture filters.
The chromatographic workstation has method unlimited storage/recall function, which can easily switch analysis methods when analyzing different types of samples.
