Abstract
Data of a plurality of samples collected by an LC/MS, GC/MS or other systems are converted into a two-dimensional table format. After LC/MS measurement data on a plurality of samples are obtained and the respective extracted ion chromatograms (XICs) are created, a time-axis adjustment for correcting a discrepancy in the retention time is performed, followed by a process of correcting the missing of data which has occurred in the head and/or tail section of the data as a result of the time-axis adjustment.

An analysis data processing method for processing a plurality of chromatogram data obtained for one sample or a plurality of chromatogram data respectively obtained for a plurality of samples, comprising:
- a) a time-axis adjusting step in which time axes of a plurality of target chromatogram data selected for a comparative analysis from the aforementioned plurality of chromatogram data are adjusted so that appearance times of the same component coincide with each other;
- b) a data rectifying step in which, if there is a chromatogram data having an incidence of missing data at a point in time within a head section and a tail section of the plurality of target chromatogram data after the time-axis adjustment, the plurality of target chromatogram data is rectified by deleting data included in a time range where the missing of data has occurred;
- and
- c) a table creating step in which the plurality of target chromatogram data that have undergone the data rectifying step on the head section and the tail section are compiled into a two-dimensional table with data values of each chromatogram data arranged in order of time in a longitudinal or lateral direction and the target chromatogram data arranged in a lateral or longitudinal direction orthogonal to the time-order direction.
