REMOVING METHOD OF CORROSIVE GAS IN GAS CHROMATOGRAPHY FOR INORGANIC GAS ANALYSIS AND COLUMN THEREFOR

摘要

PURPOSE:To prevent corrosion of the device and enable high accurate analysis by removing chlorine gas with silver iodide, and passing inorganic gas to be analysed but catching I2, and hereafter passing it through a filler column. CONSTITUTION:In a corrosive gas removal column 4A for gas chromatography to analyse inorganic gas such as O2, N2, CO2, CO in the gas to be detected containing chlorine gas, a silver iodide filling part 8 is arranged on the gas introducing port 5 side, and a filling part 9 to pass through analysing object gas to be detected but catch I2 is arranged on the gas discharge port 6 side. Hereby, corrosive gas is removed, corrosion of the device is prevented, and accurate analysis can be performed in a long time.
