01 Solution Summary
Sulfur hexafluoride insulating gas enters a dedicated GC flow path through leak-tight sampling and gas valve quantitative injection, where sulfur hexafluoride decomposition products are separated and determined. The following arrangements are used for quantification and quality control: for sulfur hexafluoride decomposition products, calibration relationships are established using reference materials matched to the detection channels, and the identification basis, quantification method, and result units are based on the applicable method; blanks, calibration checks, parallel samples, and quality control samples form batch quality control. Each analytical batch also includes blanks, calibration checks, and applicable quality control samples.
