Abstract: Helium ionization gas chromatograph is suitable for the detection of trace impurities in high-purity gases and gases used in the electronics industry. The products have been awarded the Shanghai high-tech achievement transformation A-level project, Shanghai key new products, Shanghai Torch Plan and 2009 Excellent titles such as scientific instruments. Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in samples of surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid sediments and atmospheric particulate matter, and traces in water and reagents related to the microelectronics industry Analysis of the amount of impurities. In addition, it is also widely used in the fields of food, health, petrochemical, water and geology. Common ions that are frequently detected are: Anions: F-, Cl-, Br-, NO2-, PO43-, NO3-, SO42-, formic acid, acetic acid, oxalic acid, etc. Cations: Li, Na, NH4, K, Ca2, Mg2, Cu2, Zn2, Fe2, Fe3, etc. Ion chromatograph separation and determination of common anions is its specialty. A sample is injected, and the measurement results of 7 common ions can be obtained within about 20 minutes, which is beyond the reach of other analytical methods. Chromatography does not show superiority compared with AAS and ICP. Helium ion chromatograph related products: GC-9560-HG Helium Ionization Gas Chromatograph GC-9560-HG Silane Purity Analysis Helium Ion Gas Chromatograph Product features: GC-9560-HG helium ionization gas chromatograph is suitable for the detection of trace impurities in high-purity gases and gases for the electronics industry, with a minimum detection concentration of up to 5ppb. The instrument is equipped with a highly sensitive helium ionization detector, adopts Huaai's first-class center cutting technology, and the sampling valves are equipped with a purge protective gas path; the whole machine adopts a multi-column design and is equipped with an automatic correction system for injection pressure. Ensure that the injection volume of samples with different bottom gas is consistent. Gloabl Sports Equipments Co.,Ltd , https://www.sandingarchery.com
