ABSTRACT:
A two-dimensional fluorescent densitometry for measuring a specimen plate having a specimen spot such as phospholipide two-dimensionally developed and fluorescent-labelled on a TLC plate. The densitometer comprises an excitation optical system for scanning a measuring plate with an excitation light beam, a fluorescence detection system for detecting a fluorescence from the measuring plate, a correction table for storing fluorescent data together with positional information in a scanning direction on the measuring plate, and an arithmetic section for dividing fluorescence detection data by fluorescent data at the same position in the scanning direction on the measuring plate stored in the correction table.
