This product uses gold wire enrichment-cold atomic absorption spectrophotometry. Hg in the sample gas is enriched through gold wire, and then the enriched gold wire is thermally decomposed to quickly release gaseous Hg. Based on that Hg selectively absorbs ultraviolet light at 253.7nm, the Hg concentration in sample is obtained.
It has two channels that can be measurement channel and reference channel separately, and the measurement signal and reference signal are collected at the same time to improve the accuracy of the analyzer.
With intelligent range switching function, the analyzer can automatically switch the high and low range optical path channels according to the mercury content in the air to achieve a balance between range and sensitivity.
It adopts dual enrichment and analysis device with enrichment and analysis time less than 3min. The device is switched to use, thus ensuring the continuity of sampling, while improving the data update speed.
It uses high-purity nitrogen for purge analysis, thus avoiding interference from organic matter, such as SO2, NOx, O3.
This product can be applied to online monitoring of the ambient air, indoor air, and industrial waste gas. It can be used to evaluate the regional atmospheric mercury emission, thus improving the atmospheric pollution prevention and control. It has been applied component stations and some smelters in the Chuxiong City of Yunnan Province.
