Abstract

A data processing device that processes three-dimensional data having time, intensity, and wavelength collected from a sample serving as a measurement target includes: a chromatogram generator configured to generate a chromatogram from the three-dimensional data; a target peak determiner configured to determine a target peak from peaks appearing on the chromatogram; a time point specifier configured to specify a time point at which the size of a spectrum matches the size of a reference spectrum from a time range during which the target peak appears in the three-dimensional data; and a target spectrum generator configured to extract data at the time point from the three-dimensional data, thereby generating a spectrum at the time point. With this configuration, a spectrum that is not affected by distortion, saturation, or noise can be readily and reliably obtained from the three-dimensional data obtained through sample analysis.

Dependent claims

A data processing device that processes three-dimensional data having time, intensity, and a third dimension collected from a sample serving as a measurement target, the data processing device comprising:

a) an intensity-time graph generator configured to generate an intensity-time graph with the intensity and the time plotted on axes from the three-dimensional data;
b) a target peak determiner configured to determine any one peak from peaks appearing on the intensity-time graph to be a target peak;
c) a time point specifier configured to specify a time point at which a size of a spectrum with the intensity and the third dimension plotted on axes matches a predetermined value from a time range from a start time point to an end time point of the target peak in the three-dimensional data;
and
d) a target spectrum generator configured to extract data at the time point from the three-dimensional data and generate a target spectrum with the intensity and the third dimension at the time point plotted on axes.
