Abstract
The present invention provides a liquid chromatographic analyzer for analyzing a sample containing components for analysis by reacting the sample with a pre-labeling reagent to obtain a reaction mixture containing labeled components, concentrating the reaction mixture and separating the labeled components from each other, and detecting the separated labeled components by a detector, the steps of analysis being controlled to concurrently proceed by a control unit, thereby shortening the time for analysis per sample which analyzer includes: (a) a unit for storing samples containing components for analysis and a pre-labeling reagent for the components at a constant temperature, (b) a unit for reacting the sample with the pre-labeling reagent at a constant temperature to obtain a reaction mixture containing labeled components, (c) a unit for transferring one of the samples and the pre-labeling reagent from unit (a) to unit (b), (d) a unit for concentrating the reaction mixture and separating the labeled components from each other, (e) a unit for detecting the separated labeled components, and (f) a unit for controlling the steps of analysis to concurrently proceed, thereby shortening the time for analysis per sample.
