This instrument is a multi-functional portable water quality testing device that integrates conventional water quality item testing, biological toxicity testing and rapid ATP testing. It can be used for on-site rapid screening and emergency monitoring, as well as for routine laboratory analysis and many other application scenarios.
1. Conventional water quality items: The instrument performs quantitative water quality analysis based on the multi-wavelength spectrophotometric principle. Its multi-wavelength LED light source system (covering 420~860 nm) is preset with the optimal analysis wavelength according to national standard methods, ensuring the specificity and accuracy of detection. During testing, the user uses the matched premade reagents; after the color reaction of the water sample is completed, the colorimetric tube or test bottle is placed in the measuring chamber. According to the Lambert-Beer law, the instrument automatically matches the internal preset standard curve, thereby directly calculating the detection values of items such as COD, total phosphorus, total nitrogen and ammonia nitrogen.
2. Biological toxicity detection: Luminous bacteria continuously emit visible fluorescence during normal metabolism, and the luminous intensity is positively correlated with bacterial metabolic activity. When toxic substances are present in the water sample, bacterial metabolism is inhibited and the luminous intensity decreases accordingly; the stronger the toxicity of the sample, the greater the decrease in luminous intensity, showing a good negative correlation. The instrument quantitatively evaluates the acute toxicity level of the sample by precisely measuring the change in luminous intensity of the luminous bacteria before and after contact with the sample.
3. Rapid ATP testing: ATP testing is based on the firefly luminescence principle, using the "luciferase-luciferin system" to rapidly detect adenosine triphosphate (ATP). The ATP swab contains a lysis solution that can release ATP from microbial cells and cause a luminescence reaction with the specific enzyme in the reagent. Since all living cells contain ATP, the ATP content can clearly indicate the amount of microorganisms and other biological residues in the sample; the number of microorganisms is proportional to the luminescence value, which can be used to judge the sanitary condition.
It can be used for the detection of conventional water quality items such as COD, total nitrogen, total phosphorus, turbidity and other configured water quality items for on-site detection and laboratory comparison analysis.
It can be used for rapid screening and quantitative/semi-quantitative evaluation of the comprehensive toxicity of water samples, including surface water, industrial wastewater, domestic sewage and emergency accident water samples.
It can be used for rapid ATP testing to quickly evaluate sample cleanliness, microbial contamination trends or on-site sanitary conditions.
