Description

Technical Field

[0001] The present invention relates to the technical field of chemical detection, in particular to a sample adding device for a chemiluminescence analyzer. Background Art

[0002] Chemiluminescence is a new, rapid, and sensitive instrument developed in recent years. Its principle is based on the fact that certain substances undergo chemical reactions at room temperature, generating excited intermediates or products. When these products return from the excited state to the ground state, they emit photons. Because the energy of the excited state of a substance comes from the chemical reaction, it is called chemiluminescence. After the separated components are eluted from the chromatographic column, they are immediately mixed with an appropriate chemiluminescent reagent, initiating a chemical reaction that causes the luminescent substance to emit radiation. By measuring the intensity of this light, the concentration of the substance can be calculated.

[0003] When using current chemiluminescence analyzers, most testing personnel place sample reagents into a test tube, then stir the sample raw materials in the test tube, and then place it on the detection disk in the chemiluminescence analyzer. The chemiluminescence analyzer then detects the sample. After the test is completed, the sample is taken out and the next sample is tested.
