Portable Biological Toxicity Analyzer HM-DX

Product Overview:

The portable biological toxicity analyzer is a new generation of biological acute toxicity analyzer for laboratory use. It is a toxicity detection system based on bioluminescent sensing technology. It performs qualitative and quantitative detection based on the changes in the luminous intensity of luminous bacteria during metabolism. Compared with traditional fish, water fleas and other aquatic organisms as biological detection methods, the luminous bacteria method is simple, rapid, sensitive, adaptable, repeatable, accurate, low-cost, and widely used. It is a rapid water quality toxicity detection instrument designed for environmental pollution, emergency accidents, security inspections and routine inspections. It can be used for the overall toxicity detection of heavy metals, poisons, nerve agents, pesticide preparations and other substances in on-site water.

It complies with the national standard "GB/T15441-1995 Determination of acute toxicity of water quality-luminous bacteria method" and international standards (ISO11348-3).

2. Application industries:

Biological pollution, toxic chemicals, toxic and hazardous waste, municipal drainage, rainwater detection, drilling fluid and mud detection, mining industry, wastewater, soil and water detection, industrial wastewater discharge detection, process water detection, seawater detection, medical/pharmaceutical product detection, food packaging detection, personal care products and household chemicals detection, sediment detection, rainwater runoff detection, solid sample detection, food processing water detection;

Detection principle:

The portable water quality biological toxicity detector performs dual functions: toxicity testing and determining microbial contamination; toxicity testing is performed using luminescent bacteria that exist in nature. This bacteria emits light during normal metabolism. If placed in a toxic environment, their cell respiration process is affected, resulting in a decrease in the amount of light emitted. The luminescence detector measures the amount of light emitted by the luminescent bacteria before and after exposure to the toxic environment. The degree of reduction in the amount of light corresponds to the strength of the toxicity. The test results can be compared with the standard toxic substances HgCl2 or zinc sulfate heptahydrate to obtain the corresponding toxicity level.
