PURPOSE:To enable measuring of various types of analysis items by means of a single photometer, by a method wherein a light, transmitting through a reaction liquid in a housing part, is dispersed by a dispersing device, and the dispersed lights are individually detected by detectors positioned corresponding to a plurality of wavelength positions. CONSTITUTION:Reaction receptacles 7, into which a sample and a reagent are poured by means of pipettes 2, 3 are distributing devices 15-20, are irradiated with light from a light source 23 in a state that they are positioned in liquid in a constant temperature tank 22, and the transmission light is dispersed by a dispersion device 25 to detect it by means of a plurality of light detectors 26. When a measurement sample, being related to a measuring item, reaches a measurement position, a selection switch 29 is actuated by a controller 21 to select signals of required wavelengths lambda1 and lambda2. The wavelength signals are inputted to a counting circuit 31 through a function conversion circuit 30, and analyzed results are indicated in an indicator 32. This permits the analysing operation of a plurality of analysis items without the need for a mechanical moving part, and enables the miniaturization of a photometer. |
