AUTOMATIC ANALYZER AND AUTOMATIC ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an automatic analyzer capable of improving S/N ratio characteristics of a light reception signal by reducing an influence of a scattered light of a noise component other than an object to be measured.

SOLUTION: A plurality of detectors 204 to 206 obtain data at a plurality of angles. A detected data selection part 18a selects a signal obtained by one of the detectors as a reference signal. An approximate expression selection part 18b1 in a first selection data processing part 18b selects an approximate expression to be applied, and an approximate expression calculation part 18b2 calculates the approximate expression by using the selected approximate expression. A variation coefficient calculation part 18b3 determines a coefficient of variation of the reference signal. A signal from the detector 205 is held by a second selection data processing part 18c and is corrected by dividing by the coefficient of variation of reference signal in a data correction part 18d. A concentration operation processing part 18e performs a concentration operation by using the corrected signal data, and a result output part 18f outputs a result to a CRT or the like.
