ABSTRACT:
In a gas chromatograph, an injected sample for analysis (3) is passed through a separation device (5) to separate components present in the sample; at the end of the separation device, selected components are detected by a detector (12) and determined quantitatively on the basis of the detector signal (13) supplied by the detector. To permit validation and also to increase the accuracy of the analysis, the sample (3) is determined nondestructively by an additional detector (16) upstream from the separation device (5) and is determined quantitatively on the basis of the additional detector signal (17) supplied by the additional detector (16). The result of the quantitative determination of the sample (3) is used to verify the analysis.
