ABSTRACT:
An eluant is supplied to an analyzer column, a sample solution is supplied through a sample inlet. The analyzer column separates the components of the sample solution. The separated components are eluted by the analyzer column, the eluted components are detected by an eluted component detector, the results of detection provided by the eluted component detector is processed by a data processor to produce a liquid chromatogram having peaks indicating the components of the sample. The components of the sample is supplied through a capillary pipe to an ion source and the ion source ionizes the components of the sample. A mass spectrometer subjects the ions produced by the ion source to mass analysis, an ion detector detects the ions included in a mass spectrum to produce an ion chromatogram having peaks. A time difference between the chromatograms is determined beforehand through an experiment using a standard sample, and the liquid chromatogram is shifted on its time axis by the time difference.
