Characteristic Evaluation of Gas Chromatography with Different Detectors for Accurate Determination of Sulfur Hexafluoride.

ABSTRACT: Sulfur hexafluoride (SF₆), which survives in the atmosphere for an extremely long period of time, is the most potent greenhouse gas regulated under the Kyoto Protocol. So, the accurate monitoring of atmospheric SF₆ plays an important role in the study of the control policies for reducing greenhouse gas emissions. The instruments for SF₆ measurement are typically calibrated using certified reference materials. The concentrations of the commercially available SF₆ reference materials usually have a broad range, from 1 μmol/mol to 6000 μmol/mol. Some characteristics including sensitivity, linear range, relative standard deviation, and accuracy are crucial for the determination of SF₆ in such a broad concentration range. Therefore, the sele
