ABSTRACT:
A sample treatment apparatus includes a sample sucking section, a sample concentration detecting section, and a sample condensing section. The sample concentration detecting section detects a change of the quantity of light emitted from a light source by a light receiving element to measure the quantity of light absorbed or scattered by the particle component in a sample. The signal detected by the light receiving element is processed by a sample concentration controller and the approximate particle concentration of the sample is obtained. The sample condensing section is provided with a syringe and a filter unit, and the sample to be transferred from a chamber to the syringe is condensed in the filter unit.
