Problems solved by technology

At present, liquid concentration detection methods mainly include chemical titration, spectroscopy, spectrophotometry, optical rotation, resonance method, and fluorescent probe method. These methods and related detection instruments have the advantages of mature technology and high detection accuracy, but these instruments The device has disadvantages such as high price, large volume, and high requirements for environmental conditions. It needs to be used in the laboratory, and cannot meet the needs of carrying and testing liquid immediately after sampling in the field.
In some current special applications, it is necessary to sample the researched liquid object in the field and immediately detect the concentration of the sampled liquid. The previous liquid concentration detection methods and devices are difficult to meet this requirement
