About This Product
By adopting a new measurement route (patent pending), mercury vapor is routed to the absorption cell using the reduction vaporization method and the mercury collection tube-thermal vaporization method, making it possible to measure liquid and gas samples with one device. Therefore, it has excellent cost performance.
■Principle
With the addition of options, this system can measure three combinations of liquid and gas samples. Liquid samples are measured using the reductive vaporization method after wet pretreatment. Furthermore, by adding the gold amalgam method and the reduction vaporization-gold amalgam method, even more accurate measurements can be performed.
On the other hand, for gas samples, after sampling mercury in the gas with a mercury collection tube, this mercury collection tube is loaded into a mercury collection tube baking furnace, and measurement is performed using the mercury collection tube heating vaporization method described in MD-700C. You can do it. This device is a useful system when the laboratory is small and installation space is limited.
When using it to measure liquid samples and gas samples, there is no need to purchase two models, resulting in a high economical effect.
■Features
・Equipped with both MD-700B and MD-700C functions, this is a mercury measurement device for liquid/gas samples that no other company has.
- The mercury gas inlet for liquid samples and the mercury gas inlet for gas samples are different, so even if the piping is contaminated by acid mist generated when measuring liquid samples, mercury will not be adsorbed when measuring atmospheric mercury. .
■Applications
・Environment (water and sewage, river water, lake water, seawater, sediment, wastewater, soil acid elution solution, etc.), living organisms, living organisms (blood, urine, hair, etc.), samples, industrial products (RoHS-related substances, etc.) Fluorescent lights Measurement of mercury concentration in waste samples, etc.
・Measurement of mercury concentration, such as mercury quantification in back-extraction solutions from organic solvents to aqueous layers.
・Measurement of mercury concentration in exhaust gas, general ambient air, working environment gas, soil gas samples, etc.
