It is necessary to analyze outgas in transformer insulation oil in power plant facilities. Shimadzu offers a System GC compliant with ASTM D 3612 Method B (oil stripper sampling) or ASTM D 3612 Method C (headspace sampling). The Nexis GC-2030TOGAS3 system, equipped with a PDHID, enables the analysis of more trace amounts of permanent gas than conventional systems.
