Liquid chromatographic analysis apparatus and liquid chromatographic analyzing method

摘要

In a chromatograph comprising a pump, a sample injecting unit, a column, a photo-diode array detector and a data processing unit having a spectrum library of registered spectrums of known components, a spectrum selected in advance from the spectrum library is compared with a spectrum of each of peaks in an actual sample. Thereby, it is possible to reduce the number of spectrum comparisons required for identification, and it is further possible to perform identification quickly since the identification can be performed during analysis.
