AUTOMATIC ANALYZER AND AUTOMATIC ANALYSIS METHOD
First Claim
1. An automatic analyzer which irradiates a reaction container in which a sample is accommodated with light from a light source, allows an optical detection means to detect the light which has passed through the reaction container, and allows an arithmetic processing unit to analyze the sample in the reaction container on the basis of the detected light, wherein:
- the detection means has a plurality of optical detection elements that are arranged at respective different angles with respect to the light source; and
the arithmetic processing unit calculates reference data on the basis of a signal measured by one detection element selected from among the plurality of detection elements, then calculates a degree of variability of the measurement signal of the selected one detection element with respect to the calculated reference data, and corrects a measurement signal of a detection element which differs from the selected one detection element, on the basis of the calculated degree of variability, whereby the sample is analyzed on the basis of the corrected measurement signal.

Abstract
An automatic analyzer is capable of reducing the influence of scattered light having noise components to enhance the S/N ratio properties of a light reception signal. Data is obtained at a plurality of angles by a plurality of detectors and a signal obtained by one detector selected from among the detectors is selected as a reference signal. An approximation is applied by an approximation selection unit, and an approximation calculation unit calculates an approximation using the selected approximation. A degree of variability of the reference signal is determined and a data correction unit corrects the signal of the detector by dividing the signal of the detector by the degree of variability of the reference signal. A concentration calculation processing unit performs the concentration calculation by use of the corrected signal data, and a result output unit outputs the results on a display.
