ABSTRACT:
A method for automatically detecting waste gas. The waste gas is led into a multiple switching valve through which the waste gas is sampled. Then, the waste gas sample is conveyed to an empty column and/or a chromatographic column, via the multiple switching valve. Then, the total hydrocarbon content of the waste gas sample is measured when the waste gas sample is conveyed to the empty column, and the waste gas sample is separated for measuring individual volatile organic compound concentrations of the waste gas sample when the waste as sample is conveyed to the chromatographic column.
