PURPOSE:To make dispensing of various materials from materials to be treated of grain sizes smaller than specific sizes and material groups having the same substrate as that of said materials possible by immobilizing the materials to be measured on particles of different sizes by utilization of antigen antibody reaction and separating the immobilized particles by sizes. CONSTITUTION:Materials to be treated (antibodies D, etc.) such as protein which are fine particles of >=5mu making separation by sizes difficult and antigens A binding specifically with the material groups having the same substrate as that of said materials are stuck on beads B of glass, polyacrylic amide, etc. of different sizes, and the antibodies D are bound with the bodies stuck with said antigens, by antigen-antibody reaction. The suspension 1 of the bound bodies C1, C2-Cn of different sizes is fed to the nozzle N of a flow sight meter, and is dropped through a micronozzle 6. The drops are dispensed in vessels 10, 11... by the sizes of the bodies C1-Cn in the dropped liquid by the electric fields between deflecting electrodes E1-E2. Thus the materials to be measured are analyzed after the interfering factors are removed. |
