Product Overview:
The HD-DX water quality biotoxicity analyzer is a new generation of acute toxicity analyzer used in laboratories. It is a toxicity detection system based on biological fluorescence sensing technology, which qualitatively and quantitatively detects the changes in luminescence intensity of luminescent bacteria during metabolism. Compared with traditional biological detection methods such as fish, water fleas, and other aquatic organisms, the luminescent bacteria method is simple, fast, sensitive, adaptable, repeatable, accurate, low-cost, and widely used. It is a water toxicity rapid detection instrument designed for environmental pollution, emergency accidents, security checks, and routine testing purposes, and can be used for overall toxicity detection of heavy metals, toxic agents, nerve agents, pesticide formulations, and other substances in water on site.
Compliant with the national standard "GB/T15441-1995 Determination of Acute Toxicity of Water Quality - Luminescent Bacteria Method" and international standard (ISO 11348-3).
Application industry:
Biological pollution, toxic chemicals, toxic and hazardous waste, municipal drainage, rainwater testing, drilling fluid and mud testing, mining industry, wastewater, soil and water testing, industrial wastewater discharge testing, process water testing, seawater testing, medical/pharmaceutical product testing, food packaging testing, personal protective equipment and household chemical testing, sediment testing, rainwater runoff testing, solid sample testing, food processing water testing;
Detection principle:
The HD-DX biotoxicity detector performs dual functions: toxicity testing and determination of microbial contamination; Conduct toxicity testing using luminescent bacteria found in nature, which emit light during normal metabolic processes. If placed in a toxic environment, their cellular respiration process is affected, resulting in a decrease in luminescence. The HED-DX luminescence detector measures the luminescence of luminescent bacteria before and after exposure to toxic environments, and the degree of reduction in luminescence corresponds to the strength of toxicity. The detection results can be compared with the standard toxic substances HgCl2 or zinc sulfate heptahydrate to determine the corresponding toxicity level
