DETECTION OF GAS IMPURITIES WITH A GAS CHROMATOGRAPH

摘要

Detection system and method for the measurement of gas impurities in a gas sample with a gas chromatograph. The system comprises a plasma emission detector; a gas chromatograph; a vacuum pump for the plasma emission detector; a moisture permeation device to create moisture and add the moisture to the plasma emission detector by bypassing the gas chromatograph; a microcontroller device to control operation of the detection system, the microcontroller device controlling the pressure of the plasma emission detector using the vacuum pump and the moisture added to the plasma emission detector using the moisture permeation device.
