Abstract
A cell storing a sample prepared by adsorbing an immunocomplex which is formed by antigen-antibody reaction on a surface of a noble metal colloid such as a gold colloid as an immunity test material is irradiated with excitation light from a light source by an optical system. Raman scattering light generated from the sample is guided to and detected by a spectral detector through an optical system. A signal processing arithmetic unit corrects the Raman scattering light which is detected by the spectral detector with an output of the detector indicating intensity of the light source for obtaining a Raman spectrum, thereby identifying or determining a measuring object material.
