Measurement principle:
The portable biotoxicity analyzer uses luminescent bacterial reagents, which emit light during metabolism. When these bacteria are exposed to toxic environments caused by heavy metals, other organic compounds, and microorganisms, their emitted light is inhibited. The stronger the toxicity, the stronger the inhibitory effect on the metabolism of luminescent bacteria, and the more obvious the inhibition of luminescence. Based on changes in their light intensity, the toxicity of the sample can be quickly and accurately tested.
Toxicity analyzer reagent:
Made from luminescent bacteria through advanced strain screening and freeze-drying procedures. This bacterium is highly sensitive to toxic substances, and a portable biotoxicity analyzer uses heavy metal buffer or organic buffer to determine the source of toxic substances. By using these two buffer solutions, sensitivity can be improved to sub mg/L. The luminescent bacterial reagent can be stored for up to 7 days and has a wide range of usage temperatures.
Reagent composition:
1. Sealed bottle freeze-dried luminescent bacteria
2. Positive quality control standard solution: copper chloride and sodium chloroacetate
3. Test tube
4. Storage buffer solution
5. Heavy metal buffer solution
6. Organic buffer solution
Performance characteristics of portable biotoxicity analyzer:
1. High sensitivity, capable of monitoring very low concentrations
2. Can detect a wide range of pollutants
3. Chinese interface, user-friendly and friendly
4. Fast and reliable, results can be obtained in a few minutes
5. Portable and convenient, suitable for outdoor on-site testing
6. No strict environmental conditions required, strong adaptability
7. Identify heavy metals and organic compounds
8. Luminescent bacteria can be stored for a long time
Application scenarios:
Especially suitable for monitoring the toxicity of drinking water and food, and for rapid detection of sudden water pollution incidents. Portable biotoxicity analyzers can also be used to monitor changes in hazardous substances in pipelines, as well as the relative toxicity of influent and effluent from sewage treatment plants.
