Operation Principle:
5E-HGT2320 is a direct mercury analyzer of solid and liquid samples which employs the thermal decomposition process described in U.S. EPA Method 7473.

The samples are firstly dried, in which moisture shall be discharged in a form of vapor by a three-way valve. Then the sample is thermally decomposed in an oxygen-rich stream and the decomposition products are carried by flowing oxygen to the catalytic section of the furnace, where oxidation is completed and all interfering substances, such as halogens and nitrogen/sulfur oxides are eliminated. The remaining decomposition products are further carried to a gold amalgamator where the mercury is selectively trapped.

After the system is flushed with oxygen to remove the remaining decomposition products, the amalgamator is rapidly heated, releasing mercury vapor. Flowing oxygen carries the mercury vapor through a253.7nm wavelength atomic absorption spectrophotometer. Mercury concentration is measured via absorbance peak height or peak area.

Features:Safety FirstDetermine total mercury directly without sample preparation or other wet chemistry. No hazardous waste produced and no corrosive chemicals used.

High Efficiency
Results in 5 minutes. An auto-sampler with as many as 70 sample positions is  provided.

Wide Application5E-HGT2320 is able to analyze a variety of sample types including solids and liquid in a wide range of applications.

Easy Operation
Just input the sample mass into software and load the sample onto the auto-sampler, 5E-HGT2320 will finish the test automatically.

Minimum Analysis Cost
Compared with the traditional CV-AAS mercury analysis techniques, 5E-HGT2320 saves more than 70% in cost for customers.
