Air quality & industrial emission Mercury monitor VM3000 - 1

Mercury Vapor Monitor VM-3000 AIR QUALITY MONITORING The VM-3000 is a continuous real-time measurement analyzer for mercury in air and other gases - in the laboratory as well as in industrial and mobile applications. MAIN APPLICATIONS  Work place monitoring  Exhaust air monitoring in mercury recovery plants  Emissions monitoring  Quality control of industrial gas  Investigation of contaminated sites  Environmental monitoring  Hazardous waste inspection  Research and science  Detector and analyzer for laboratory applications Reference UV detector Temperature control The Mercury Vapor Monitor VM-3000 is one of the backbones of our modular system for mercury analysis. MEASURING PRINCIPLE The mercury concentration is measured in an optical cell made of fused silica. Beam A maintenance-free membrane pump UV detector splitter Cell Long life continuously feeds the sample gas to heating membrane pump Pinch the optical cell where UV absorption is Zero gas ﬁlter valve Particulate measured at a wavelength of 253.7 nm. This ﬁlter so-called cold vapor atomic absorption spectroscopy (CVAAS) measuring VM-3000 Flowchart method is extremely sensitive for mercury determination and has been used successfully for many years. In contrast SPECIFIC FEATURES to the occasionally propagated atomic ﬂuorescence spectroscopy (AFS)  Easy to operate method it is low in interference and  Direct reading mercury vapor meter requires neither an amalgamation  Proven reliable detection method: UV absorption (CVAAS) step nor expensive noble gases as carriers.  Measuring ranges 0.1 - 100 / 0 - 1000 / 0 - 2000 μg/m3 UV source (EDL) Optical cell  Sensitivity: 0.1 μg/m3  Automatic zero adjustment  Integrated battery for mobile operation (option)  Integrated data logger (option)  Metal housing with sturdy handle (Rack version with mounting brackets for 19” racks as an option)  Membrane pump with long service life  Input ﬁlter with teﬂon membrane  Factor
