As we all know, water quality is easily disturbed by many factors during testing, including the quality problems of the multi-parameter water quality measuring instrument itself, other substances in the water body, and experimental utensils and other factors. It is mainly caused by other substances in the water body and residues in experimental utensils. For example, when using photoelectric colorimetry to test the content of heavy metals in water, the requirements for color reagents are very high. Choosing the right color reagent can effectively eliminate the interference between metals . After the water quality detector is operated, the experimental utensils must be thoroughly cleaned, otherwise the residual substances will directly affect the next test result. In addition, the overflow of the experimental vessel itself will also have a certain impact on the water quality test results. In the test, the experimental utensils carrying the water quality samples are mainly made of glass and plastic. Glass utensils are only used in accurate quantitative analysis, and plastic utensils are used in general testing experiments. At that time, it needs to be added in production. Various substances such as plasticizers, stabilizers, antioxidants, flame retardants, etc., and these substances will be diluted under certain conditions. The above is an analysis of the results that affect the multi-parameter water quality analyzer. If you need to know about cod digestion instrument,
