A method for analyzing antigen or antibody contained in a sample by introducing a first end surface of at least one measuring light guide member and a second end surface of at least one reference light guide member in the sample. Each of said measuring and reference light guide members being coated with a protection layer except for said first and second end surfaces and an other end surface of respect light guides. Only on said first end surface of the measuring light guide member being fixed an antigen or antibody which is specifically reactive with the antigen or antibody contained in the sample to effect an antigen-antibody reaction. Photoelectrically detecting optical properties of said first and second end surfaces of the measuring and reference light guide members, respectively, by transmitting light through the meauring and reference light guide members to derive detection signals as a measure of antigen or antibody in the sample. Further, when first and second measuring light guide members having A-type antibody and B-type antibody fixed onto one end surfaces thereof are used, a blood type of a blood sample can be determined by detecting the optical condition of the one end surfaces of the first and second measuring light guide members.

Method of effecting immunological analysis and apparatus for carrying

An electrolyte in a sample is stably measured by using an automatic biochemical analyzing apparatus wherein a flame photometer is assembled, which comprises a sample pipetting and delivering member, a reagent liquid delivering member, reaction cups charging the sample delivered through the sample pipetting and delivering member and the reagent liquid delivered through the reagent delivering member and a flame photometer for measuring an electrolyte, the method being characterized in that with respect to a sample cup to which the measurement of electrolyte is ordered, the sample pipetting and delivering member and the reagent delivering member are operated to deliver the sample and the reagent liquid to a reaction cup and an electrolyte of the diluted sample in the reaction cup is measured by the flame photometer and with respect to a sample cup to which the measurement of electrolyte is not ordered, the sample pipetting and delivering member is not operated and into a reaction cup corresponding to said sample cup is delivered a liquid from a liquid delivering member and this liquid is fed into a flame photometer and automatically measured to prevent the elevation of the temperature at the flame photometer. The liquid delivered into the reaction cup may be the said reagent liquid or a liquid different from the said reagent liquid. The calibration of the measurement is made in a specific embodiment for carrying out the above mentioned method.

Method for measuring an electrolyte in an automatic biochemical

A measuring vessel for analysis utilizing a fixed enzyme is disclosed. This vessel has an inner peripheral surface at least a part of which being provided with at least one fixed enzyme, and a movable bottom portion. By applying this measuring vessel to automatic biochemical analyzing apparatus can be performed not only single channel-single item analysis but also single channel-multi item analysis.
