Abstract
A method for monitoring the concentration of at least one volatile or semi-volatile compound contained in at least one air stream carrying at least one volatile or semi-volatile compound and apparatus for performing the method, which includes the steps of calibrating at least one gas chromatograph using at least three different calibration gases, obtaining a sample of the at least one air stream containing the at least one compound, providing the sample of the at least one air stream to the at least one gas chromatograph under control of a digital data processor to analyze the sample of the at least one air stream to determine the concentration of the at least one compound in the sample and controlling the operations using the digital data processor.
