Standard Test Method for Air and Carbon Tetrafluoride in Sulfur Hexafluoride by Gas Chromatography

Importancia y uso:

4.1 Air and carbon tetrafluoride (CF₄) are two contaminants of interest in sulfur hexafluoride (SF₆). Both of these contaminants adversely affect the performance of SF₆ when used as an electrical insulating gas. Specification for maximum levels of these contaminants are given in Specification D2472.

4.2 Gas chromatography is used to separate these contaminants from a sample of SF₆ and to determine their concentration.
