Description

I. Introduction of Gas Chromatography Insulating Oil Chromatographic Dissolved Gas Analyzer

HZGC-1212 electric power special gas chromatography using the national standard recommended three

detector processes. An analysis of the contents of seven components (H2, C2H2, C2H6, C2H4, CO, CO2,

CH4, ) in the insulating oil. When the minimum detection concentration satisfied for 1mL, per unit volume of oil

contained volume of gas is: H2≤2ppm,C2H2≤0.1ppm,CO,CO2≤2 ppm,Qualitative repeatability: Deviation≤1%;

Quantitative repeatability: Deviation≤3%.
