QM208B atomic absorption Direct mercury analyzer is a specialized instrument for laboratory gas mercury analysis. Complies with the JB5228-91 mercury analyzer standard.
It has the advantages of easy operation and high sensitivity. Due to the use of a constant light path, the changes in the light source cancel each other out, increasing long-term stability. Using a microcontroller to control the automatic switching of solenoid valves, the measurement state is a closed-loop gas path, and the cleaning state is an open-loop gas path. This makes the measurement data stable and the pipeline easy to clean. Adopting constant temperature absorption cell technology makes the test more stable. During the test, mercury containing gas continuously passes through the sample cell, and a data is obtained in 2 seconds.
Complies with the mercury testing requirements of HJ543, HJ597, HJ917, HJ923, DZ/T0064.26; When selecting liquid for manual injection, multiple injection volumes are supported, including 5mL, 20mL, and a maximum of 200mL. The light detection cell adopts a high and low concentration dual cell; Expanded the testing range
1. Excellent baseline stability
2. Has excellent short-term and long-term accuracy
3. Two point calibration and concentration direct reading methods can be used
No need for argon or nitrogen as carrier gas, suitable for working environments where argon and nitrogen are used unconditionally. The gas flow rate for measuring and cleaning is automatically adjusted
