Problems solved by technology

[0002] In the existing technology, the relatively mature technology is to detect the content of the target components measured in the bagged complex solution through chemical inspection, which has the outstanding advantage of high accuracy, but the method of chemical inspection cannot meet the requirements of fast, non-contact, and Due to its non-contact and non-polluting characteristics, it is also possible to realize the content detection of the target components measured in the complex solution in the packaging bag due to the requirement of no pollution.
[0003] In view of the complexity of complex solution components, pure transmission spectrum can obtain the information of all complex solution components, which is poor in pertinence
In order to further improve the measurement accuracy of the target components measured in complex solutions, combined with the strong pertinence of fluorescence, but due to the strong scattering of complex solutions and other factors that cause spectral nonlinearity and the influence of spectral background noise, it cannot respond well to the measured characteristics of matter
