An Improved ASTM D3612 TOGAS System by Shimadzu

ASTM D-3612 is a gas chromatography (GC) method that describes the analysis of hydrogen, oxygen, nitrogen, methane, carbon monoxide, C2-C3 in hydrocarbon-based transformer oil. In this study, two changes were made to the method. The first was substituting a universal Barrier Ionization Discharge (BID) detector in place of a TCD; hydrogen detection levels were lowered from 10ppm to 100ppb. The second change was the addition of propane and butane into the analysis.
