Liquid chromatograph and method for correcting detector output value fluctuation of liquid chromatograph

A method for correcting detector output value of a liquid chromatograph, the method comprising:

• selecting an analysis condition for using a liquid chromatograph, the analysis condition being selected from preset recipes that are registered in advance according to an examination object, the analysis condition being a condition to be set with respect to devices included in the liquid chromatograph such as a pump, an auto sampler, a column oven, and a detector,
• starting analysis according to the analysis condition that is selected in the previous step, measuring a characteristic of a sample using the detector, the characteristic including at least one of an absorbency and a fluorescence amount, and storing and displaying a signal strength of the detector indicating the characteristic of the sample in relation to time as analysis results;
• obtaining a chromatogram;
• recognizing peaks included in the chromatogram;
• determining a most minute peak of the signal strength of the analysis results in peaks which are recognized as a correction target peak;
• determining correction candidate wavelengths with respect to the correction target peak;
• performing a correction process on detector output value fluctuation based on correction method which is selected from among a plurality of preset correction methods;
• and
• outputting the analysis conditions, the correction condition, and corrected results of the characteristic of the sample.
