Scope
This document specifies the methods and principles, reagents and materials, instruments and equipment, and measurement steps for determining the purity of perfluoroisobutyl nitrile (also known as heptafluoroisobutyl nitrile (C4F7N)) gas using gas chromatography-pulsed discharge helium ionization detection (GC-PDHID), gas chromatography-mass spectrometry (GC-MS), and gas chromatography-thermal conductivity detection (GC-TCD). This document is applicable to the purity determination of new perfluoroisobutyl nitrile gas used in electrical equipment. The determination of gas purity during operation can be used for reference.
