Background

Chemiluminescent analyzers, also known as chemiluminescent immunoassay devices, are immunoassay methods in which antigens or antibodies are directly labeled with a chemiluminescent agent. The chemiluminescence analysis system is characterized in that a chemiluminescent substance is catalyzed by a catalyst and oxidized by an oxidant to form an excited intermediate, when the excited intermediate returns to a stable ground state, photons (hM) are emitted simultaneously, and the light quantum yield is measured by a luminescent signal measuring instrument. The immune reaction system is to directly label a luminescent substance (an excited state intermediate generated under the excitation of a reactant) on an antigen (chemiluminescent immunoassay) or an antibody (immunochemical immunoassay), or to act an enzyme on a luminescent substrate.

Because the chemiluminescence analysis does not use any light source, the interference of background light and stray light is avoided, the noise is reduced, and the signal to noise ratio is greatly improved, therefore, the chemiluminescence analysis method generally has high sensitivity, and chemical components of nanogram or picogram can be measured generally; the intensity of chemiluminescence is measured by using a photoelectric conversion device, a function recorder or a digital display device, and the relative intensity of chemiluminescence is recorded. Quantifying the concentration of the measured component with the maximum luminous intensity (peak height of the curve); flow injection chemiluminescent meters are also widely used due to the development of flow injection analysis (fia) technology; the microcomputer system is equipped, the automatic sample injection, the record storage and the printing result are realized, and the chemiluminescent analysis speed is higher.

In the detection of the sample luminous intensity of the chemiluminescent reagent strip, a common photon value detection module is fixed position detection, and due to factors such as processing and assembly errors, the detection positions of equipment among different batches are inconsistent, the detection positions cannot be adjusted in the Z direction, so that the consistency of the detection positions among batches is caused, and the problem of inter-bench difference occurs.
