Total Mercury (Mercury Ions) Online Water Quality Analyzer
Model No.:JM-2510
Widely used in enterprise sewage, domestic sewage, surface water monitoring,
Detailed Description
1.Product overview:
The damage caused by mercury and mercury compounds is related to the amount of mercury entering the body. Mercury harms the central nervous system, the digestive system and the kidneys, and also has effects on the respiratory system, skin, blood and eyes. The most dangerous organic compound of mercury is dimethylmercury, which can be fatal in just a few microlitres on the skin.
The analyzer is capable of long-term unattended automatic continuous work according to the site settings, and is widely used in industrial pollution source discharge wastewater, industrial process wastewater, industrial sewage treatment plant wastewater, municipal wastewater treatment plant wastewater and other occasions. According to the complexity of the field test conditions, can be equipped with the appropriate pretreatment system to ensure that the test process is reliable, accurate test results, to fully meet the needs of different occasions on-site.
2.Product Principle:
This product follows the anodic dissolution method (ASV) approved by international authorities. Firstly, the analytical solution is pre-pointed under certain conditions, so that the components to be measured are enriched on the working electrode, then the solution is allowed to stand for a period of time, and then the components to be measured enriched on the working electrode are dissolved out. Due to its high sensitivity and low cost, ASV has replaced the traditional atomic absorption method in Europe and the United States, and is used in a large number of pharmaceutical, biological and environmental monitoring and analysis fields.
