QM208B atomic absorption mercury analyzer Introduction:
QM208B atomic absorption mercury analyzer, it is a laboratory mercury analyzer for gas instruments. In line with JB5228-91 mercury analyzer Ministry of standards. It retains the advantages of easy operation and high sensitivity. Due to the constant light intensity, the variations of the light sources cancel each other and increase the long-term stability. The use of single-chip control solenoid valve automatically switches to measure the state of the closed-loop gas, open state when the gas cleaning circuit. This makes the measurement data stable, the pipeline easy to clean. Adopt the thermostatic absorption cell technology to make the test more stable. When testing, the mercury-containing gas continuously passes through the sample cell and a data is output in 2 seconds. Features:
1 Very good baseline stability
2 has excellent short-term and long-term accuracy
3 can be used 2:00 calibration, direct reading concentration method
4 No argon or nitrogen as a carrier gas, suitable for unconditional use of argon and nitrogen working environment, measuring the flow of cleaning gas automatically adjust. Technical Parameters:
Measuring range: 0.1-100μg / m3
Detection limit: 0.03μg / m3
Precision: coefficient of variation ≤ 5%
Linear correlation coefficient: r> 0.997
Relative standard deviation: <5%
The QM208B Atomic Absorption Mercury Analyzer can conveniently monitor the mercury content of various industrial waste gases in real time, and also collect and measure mercury in the atmosphere.
