Standard Configuration: Computer
Integrated Catalytic Amalgamation Tube
Amalgamation Tube Resistance Wire
Low Pressure Mercury Lamp
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:Wide ApplicabilitySuitable for solid and liquid samples, Able to detect samples in 6 different levels, 0.005ng-1500ng.
Single test only takes 2-4mins, one batch includes 45 samples, and emergency samples can be inserted at any time.
Weigh sample and place it on auto feeder without digestion. Complete analysis with just one click on Start key.
Splendid Repeatability & AccuracyIntegrated catalytic-amalgamation tube ensures measurement repeatability; composite catalytic agent of high efficiency guarantees the accuracy of test results.
No need for dehydration consumables, consumable cost is 70% lower than the traditional method.
No harmful chemicals are used in the whole analysis process. The exhaust gas produced by the analysis is effectively absorbed.
