DLT 703-2015 Gas Chromatography Method for Determination of Gas Content in Insulating Oil
1、 Analysis purpose
Collect the tested oil sample according to the provisions of GB/T7597, use mechanical oscillation method or automatic headspace method to remove the gas from the oil sample, use gas chromatography to separate and detect each gas component, and calculate the results
SH/T 0713- 2002
3、 Degassing device
Automatic headspace sampler: equipped with mechanical oscillation, temperature control, pressure regulation, and automatic quantitative injection functions, and should achieve equilibrium of each dissolved gas component between the two phases within a certain period of time
