Abstract: A kit for simultaneous immunoassay of at least two items which comprises a development layer material comprising a development layer permitting development of a sample; at least two, preferably three or more, reagents supported in optional places on the development layer and individually containing an antibody or antigen different from those of the other reagents; and a concave sample-spotting place provided in the same place as one of the places where the aforesaid reagents are supported or in a place remote from all of these places. And a process for simultaneous immunoassay of at least two items which comprising utilizing said kit. The reagents supported in the above mentioned optional places are contained in microcapsules or liposomes.

Abstract: A turntable holding a train of reaction containers thereon is continuously turned by one revolution plus an angle for a share of one container and then stopped. This makes one cycle. On the route of transfer of the reaction container, there are provided a light irradiation position and a light collection position.The reaction container into which a sample and a marker reagent have been introduced is transferred such that it does not stop at the irradiation position and the light collection position. The reaction container to which a monochromatic light for excitation has been irradiated at the irradiation position is transferred toward the light collection position. Fluorescence coming from the light collection position is lead to a photodetector, and the concentration of the target substance in the sample is determined from the detected fluorescence after arithmetic processing.

Abstract: An automated analyzing apparatus with a photometer including an entrance slit permitting passing therethrough of the entirety or a portion of a convergent light beam transmitted successively through a plurality of sample measurement cells each containing a sample solution therein and a sensor converting the quantity of light passed through the entrance slit into a physical quantity which is an objective of measurement. A scattered light sensor is disposed between the sample measurement cells and the entrance slit at a position where the sensor is not irradiated with a straight advancing component of the light beam, whereby measurement of immunity-related tests on the basis of the intensity of scattered light can be made together with measurement of biochemical tests on the basis of the intensity of transmitted light.
