The product complies with HJ542-2009 Determination of Mercury in Ambient Air - Sulfhydryl Cotton Enrichment - Cold Atomic Fluorescence Spectrophotometry.
Application Scope
The TH-9010 mercury analyzer uses the principle of sulfhydryl cotton enrichment - cold atomic fluorescence method. The principle is that after the sample gas to be measured is processed by the sampling enrichment system, it enters the reaction cell of the analyzer and is irradiated by ultraviolet light (253.7nm) in the reaction cell. Since ultraviolet light can cause elemental mercury to produce ultraviolet fluorescence, the generated fluorescence is received by the photomultiplier tube on the vertical optical path, producing a photoelectric signal. The concentration of elemental mercury in the reaction cell is proportional to the generated fluorescence, and the mercury concentration can be calculated by detecting its light intensity. This product is suitable for online monitoring of gaseous mercury in fixed pollution sources and ambient air.
