DeltaTox II portable water toxicity analyzer and biological pollutant analyzer

DeltaTox IIPortable water toxicity analyzer,Specially designed for rapid and accurate detection of various water toxicity and biological pollutants on site, as well as laboratory testing needs, using luminescent bacteria - Fischer fox fungus as the detection of live organisms, detecting the intensity of light produced by luminescent bacteria to determine the presence and degree of toxicity of the tested substance. Fast detection process（5Minute by minute, comprehensive, built-in automatic temperature control, self calibrating luminosity, can minimize false alarms or omissions, and ensure the reproducibility of results. Can simultaneously detect and analyze chemical toxicity and biotoxin contamination. Can be more than2800Accurately detect harmful substances and chemicals. Can be applied to counter-terrorism, emergency response, and early warning monitoring; Comprehensive evaluation of lake basins; Safety assessment of source water and drinking water; Rapid on-site monitoring of various pollution accidents; Comprehensive evaluation of pollutant emissions; Food safety analysis; Toxicity reduction assessment（TRE’S）Toxicity identification and evaluation（TIE’S）And various sudden environmental pollution accidents.

Portable design can also be used for field testing, vehicle mounted testing, and various occasions. Easy to use and achieve results in a few minutes. Test data can be stored for later download and analysis.

l Principle of toxicity testing:

The equipment adopts a method recognized by authoritative institutions: the biotoxicity detection sensor - Vibrio fischeri luminescent bacteria is used to detect live organisms, which provides an effective detection method to deal with water pollution (whether caused by intentional destruction or sudden accidents). Due to the fact that acute toxicity testing can be conducted5～30Completed within minutes, ensuring rapid response to changes in water quality.

This bacterium emits light during metabolism. The strength of the toxicity of water samples can be expressed by comparing the degree of light attenuation with the non-toxic control blank experiment. Due to the fast testing process, the relative concentration of toxic substances in the water sample can be determined by diluting the test sample. This method can also be used to determine what treatment processes (disinfection, filtration, adsorption, heating, etc.) can eliminate or neutralize toxic substances in water.
