Toxicity analyzer is a toxicity detection system based on biosensing technology, which qualitatively and quantitatively detects the luminescence of luminescent bacteria during metabolism. It provides a fast and effective detection method for water quality and food toxicity status, which can quickly and accurately evaluate toxicity, and can provide scientific and reliable analysis results with just a few simple steps.

Application scenarios

Especially suitable for monitoring the toxicity of drinking water and food, and for rapid detection of sudden water pollution incidents. It can also be used to monitor changes in hazardous substances in the pipeline network, as well as the relative toxicity of incoming and outgoing water in sewage treatment plants.

measuring principle

The instrument uses luminescent bacterial reagents, which emit light during metabolism. When these bacteria are in a toxic environment 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

Luminescent bacteria are produced through advanced strain screening and freeze-drying procedures. This bacterium is highly sensitive to toxic substances and 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.
