Description

technical field

[0001] The invention belongs to the technical field of testing or analyzing materials by means of determining their chemical or physical properties, and in particular relates to devices in which materials are subjected to chemical reactions, and the progress of the testing reactions or the resulting chemiluminescence. Background technique

[0002] Since Ruzicka and Hansen first proposed Flow Injection Analysis (FIA) technology in 1975, flow injection technology combined with detection methods such as ultraviolet, fluorescence, chromatography, atomic spectroscopy, and mass spectrometry has been widely used in the field of analytical chemistry. application. The characteristics of fast, simple and low consumption of flow injection technology are also the goals pursued by all analytical methods. Among the analysis methods combined with flow injection technology, the luminescence analysis method shows the advantages of fast analysis speed, simple equipment, less ...
