The product conforms to hj542-2009 determination of mercury in ambient air by sulfhydryl cotton enrichment cold atomic fluorescence spectrometry.
The principle of th-9010 mercury analyzer is gold amalgam enrichment cold atomic fluorescence method. The principle of th-9010 mercury analyzer is that when the sample gas to be measured is processed by the sampling and concentration system, it enters the reaction cell of the analyzer, and is irradiated by ultraviolet light (253.7nm) in the reaction tank. The ultraviolet light can make the elemental mercury produce ultraviolet fluorescence. In the vertical light path, the fluorescence generated is accepted by the photomultiplier tube and the photoelectric signal is generated. The concentration of elemental mercury in the reaction tank is directly proportional to the fluorescence generated. The concentration of mercury can be calculated by detecting its light intensity. This product is suitable for on-line monitoring of gaseous mercury in fixed pollution sources and ambient atmosphere.
