A kind of full-automatic chemical luminescence immunoassay instrument
Technical field
The present invention relates to a kind of full-automatic chemical luminescence immunoassay instrument.
Background technology
Thereby chemical illumination immunity analysis instrument is by detecting patient's serum carries out immunoassay to human body medical test instrument.Quantitative patients serum and horseradish peroxidase (HRP) are joined solid-phase coating to be had in the White-opalescent microwell plate of antibody, the antibody specificity of testing molecule in the serum on the bond of horseradish peroxidase and solid phase carrier is combined, the unreacted free composition of separating, washing, then, add liquid of the luminous end, the free energy that utilizes chemical reaction to discharge excites intermediate, gets back to excited state from ground state, and energy discharges with the form of photon.But, existing full-automatic chemical luminescence immunoassay instrument all is be used to reading the faint light energy that 96 or 48 hole microwell plates send in the market, be used for measuring the concentration of patients serum's certain antibody of sample or antigen, so-called 96 or 48 hole microwell plates are to comprise 96 or 48 reaction cup on the plank, patients serum's sample that each need detect is placed in the reaction cup, the sample size that detects when needs has only several or needs to use a monoblock 96 or 48 hole microwell plates equally tens the time, therefore causes a large amount of wastes; On the other hand, present existing full-automatic chemical luminescence immunoassay instrument generally once can only detect a microwell plate, and second microwell plate need be put into detector again and detect after first detection finished, therefore, the speed that detects is unhappy, and staff's detection efficiency is not high; 96 or 48 microwell plate is longer in the required time of first hole of application of sample to last hole, and therefore the consistance to the result has certain influence; The structure of microwell plate can't solve the problem of hole interdigit light cross pollution fully.
