A Novel Gas Chromatography with a Pulsed Discharge Helium Ionization Detector for Measurements of Sulfur Hexafluoride Gas Sampled from Electrical Equipment

摘要

Gas chromatography with a pulsed discharge helium ionization detector has the advantages of high sensitivity, wide linear range and universal use. It detects SF6, O2, N2, H2S, SO2, SOF2, SO2F2, S2OF10, CS2, CF4, C3F8, CO2, CO and other components with single injection. Comparison with other methods, it is probably more preferable for the analysis of the sulfur hexafluoride sampled from electrical equipment and will improve the technology of SF6 electrical equipment fault and latent fault diagnostics.
