Abstract

In a two-dimensional LC system configured to introduce components trapped in a trap column during a fractionation period T into a second-dimension column, separate components, and then detect the components using a mass spectrometer, a data collection unit receives a signal which indicates timing to delimit the fractionation period T, determines the first data item in the fractionation period T, adds measurement start point identification information to the first data item, and stores all the data in a data storage unit. A two-dimensional chromatogram creation unit recognizes the first data item in each fractionation period T from the read data, and create a two-dimensional chromatogram by aligning data so that the first data items will be aligned at the top along an abscissa.
