GC112AIntroduction to Gas Chromatography:

Product name: Gas chromatograph

model:GC112A

Manufacturer: Shanghai Yidian (Shanghai Jingke Upper Branch)

The laboratory chromatograph for the analysis of eight component gases in transformer oil has been newly designedGC112AOn the basis of a universal gas chromatograph,A multidimensional gas chromatograph successfully developed through secondary development. This instrument dissolves gases in transformer oil according to the requirements of the newly issued national standardsH2、O2、CO、CO2、CH4、C2H6、C2H4、C2H2Analysis of .
This type of chromatography

GC112AMain characteristics of gas chromatograph：
