Abstract:
A chromatography comprising:a detector for detecting a sample so as to output a measuring signal according to elapsed time, an input unit for inputting a strength parameter characterizing a form of base line by an operator, a data processor for processing said measuring signal based on said strength parameter so as to output a chromatogram formed with a plurality of chromatogram data points and a base line corresponding to said chromatogram, said data processor correcting a plurality of datapoints forming said base line based on a relation of in which said strength parameter exhibits a difference in a direction of signal strength of said chromatogram between adjacent data points of said base line, and a display for displaying said chromatogram and said base line, said display having a flexibility display area for displaying said difference in direction of signal strength of said chromatogram between said adjacent data points of said base line.
