Abstract:
1. A chromatographic analyzer comprising: sample separating means for separating a sample to be measured into components; detecting means for detecting said separated sample by said separating means; data processing means for executing data processing by obtaining the detected result of said detecting means; and display means for displaying the data processing result, wherein said data processing means compr ises means for specifying an arbitrary retention time region having a plurality of peaks of a chromatogram obtained as the detected result of said detecting means; means for specifying whether fitting processing is executed from a front side end or a back side end of said specified retention time region; and means for specifying a weighting function and a waveform function used in said fitting processing and being arranged to adjust a weighting function width corresponding to inflection points within the retention time region, wherein a new retention time region, which has peaks other than those peaks at which the fitting processing is completed to define their peak shapes, is displayed on said display means, and said specifying of a weighting function is performed with conceptual graphics of candidate weighting functions superposed over said chromatogram displayed on said display means.
