DL/T 2406-2021 《Sulfur hexafluoride dissolved in insulating oil gas content detection method Gas chromatography, CG》 Related products

This document specifies the method for the determination of sulfur hexafluoride content in insulating oil by Gas chromatography, CG, including sample collection, instrumentation, operation steps and result calculation. It is suitable for the determination of sulfur hexafluoride content in insulating oil. Methods The dissolved sulfur hexafluoride gas in the insulating oil sample is extracted by a degassing device, separated and detected by Gas Chromatograph, and finally the dissolved sulfur hexafluoride gas content in the oil is calculated by the External standard method. Instruments and equipment include thermostatic timing Shaker and gas phase Chromatograph, in which Chromatography Column should meet specific requirements, such as length, inner diameter, etc.
