摘要： In measuring the signal peaks caused by unknown samples in, for example, the detector outputs of gas chromatographs, the peak signals are identified as to the unknown sample components by comparing their time of occurrence (the retention times of the sample components) to the times of occurrence of known components from a previously run known sample. The peak signals are then integrated to find their areas and each peak area is multiplied by a different stored calibration factor, in accordance with (the reciprocal of) the sensitivity of the detector to each particular sample component. Rather than determining whether the unknown sample components have a retention time within a tolerance range about the respective retention times of previously run known sample components as done in the past, the present technique uses the criterion of whether any part of the unknown peak has the same time of occurrence as the center of the known sample peak. In this manner, the effective tolerance range of the respective retention times is determined by the width of the unknown sample peak, so that the tolerance range is automatically compensated in accordance with the chromatographic operating conditions and inherent characteristics of the sample component, which affect the broadening of peaks.
