Photometric method for automatic analyzing apparatus

Abstract

Abstract PURPOSE:To make an analysis possible by illuminating the plural cells by one light source selectively at high speed without moving the light source or cell, by invading the plural number of optical path conversion members along the optical path of the light source selectively. CONSTITUTION:Luminous flux from a light source 10 is made into a parallel light passing through a lens 11 and is transmitted through a filter 14 of a filter turret 13 attached to a motor 12. Further, said light is introduced to a cell 16 for holding a liquid to be inspected by a mirror 15 and is received by a photodetector 17. The cell 16 consists of A-F eight cells and the mirror 15 consists also of eight mirrors. The mirror 15 is moved between P-Q parallelly. In order to make the analysis of eight items of the same sample, the sample is taken in eight cells 16 and the luminous flux is made incident to the cells A-F successively. Also, photometry can be carried out by the plural wavelengths by stopping the mirror 15 at the P position and switching the filter 14 successively by rotating the turret 13.
