Page No : 04 System Introduction Based on Cold Vapor Atomic Fluorescence Spectrophotometer Technology, VASTHI has developed stack mercury continuous emission monitoring system to detect the real time concentration of emission mercury and its cumulate emission rate. It is able to monitor gaseous elemental mercury, ionic mercury and total gaseous mercury. Its detection limit is low 0.05ug/m3. This system is widely applied to measure mercury concentration in the tail of gas of many industries, such as mercury minerals refining process, mercuric chloride catalyst recycling, Cola-fired power...

NVASTHI C ENGINEERS A I The system adopts the technology of Cold Vapor Atomic Fluorescence Spectrophotometer (CV AFS). The low voltage mercury lamp shots 254nm ultra-violet light on measured object with mercury vapor: the mercury atom absorbs energy and is transited to excited state from steady state. When mercury atom is transit from unstable excited state to steady state, it will radiate 254nm fluorescence and the fluorescence is proportional to mercury atom.The Fluorescence intensity is converted into electrical signals by the photomultiplier tube. After amplification and A/D...
