Title: DATA PROCESSING METHOD AND DEVICE
Abstract:
This data processing method is a method for processing the data of a two-dimensional graph in which a second parameter changes according to a continuously changing first parameter and a peak of the second parameter is on a baseline. The method includes: a baseline range demarcation step (S2, S3) for using a prescribed method to demarcate, on the graph, all baseline ranges, which are the ranges of the first parameter in which there are no peaks; a drift component estimation step (S4) for estimating, for each of the baseline ranges, a graph drift component; and an overall drift determination step (S5) for connecting the drift components estimated for each baseline range through interpolation between adjacent baseline ranges and determining a drift component for the entire graph. As a result, it is possible to appropriately extract overall baseline drift from a graph, such as a chromatogram or spectrum, in which peaks appear on a baseline.
