Operation Principle:Sample is dried by heating and burnt (pyrolysis) in oxygen or air. Its decomposed product is oxidized by the high temperature catalyst carried via oxygen. Meanwhile, interferent like halogen, nitric oxides, and sulfur oxides are absorbed by catalyst. Moisture is exhausted by pneumatic truncation, and the rest of decomposed product is further conveyed to sub-nanometer Hg-trap. Mercury atoms are selectively captured, and experience secondary atomization by heating Hg-trap. Flowing oxygen carries mercury atoms into the cold atomic absorption detector (253.7nm) for determination, and the total mercury content in the sample is directly calculated by the software.
Features:Safety FirstDetermine total mercury directly without sample preparation. No hazardous waste produced and no corrosive chemicals used.
Get results in 2-4 minutes. An auto-sampler with as many as 45 sample positions is provided.
Wide Application5E-HGT2321 is able to analyze a variety of sample types including solids and liquid in a wide range of applications.
Just input the sample mass into software and load the sample onto the auto-sampler, 5E-HGT2321 will finish the test automatically.
Minimum Analysis Cost
Compared with the traditional CV-AAS mercury analysis techniques, 5E-HGT2321 saves more than 70% in cost for customers.
All the quartz tubes can be heated, which could effectively remove moisture and eliminate the memory effect of residual mercury.
