Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. There the quantitative determination of mercury is obtained by measuring UV absorption at … If you have any questions, please contact us by e-mail (Inquiry Form). Mercury Probe: The figure below shows a picture of the mercury probe and the CV-analyzer. Due to its patented direct measuring principle all effective as well as currently discussed regulatory requirements can be fulfilled. For lakes, marshes, and ocean regions, clearly Principle of operation • Solid or liquid samples are weighed and introduced in the DMA-80 • The sample is initially dried and then thermally MA-2 Mercury Analyzer . Principle of Operation . The DMA-80 can analyze solid, liquid and gas matrices with equal precision. The cold vapor principle was first proposed by Poluektov and co-workers in 1963 [2]. Utilizing the unique resonance fluorescence of mercury, AMETEK Arizona Instrument designed an instrument that can detect ultra-low concentrations of mercury vapor while minimizing the interferences involved with atomic absorption alone. The HERMES has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g). The Jerome 431-X Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.001 to .999 milligrams of mercury vapor per cubic meter (mg/m3 Hg). Use of thermal release to obtain mercury speciation information has long been used. Using the right mercury analyzer to ensure that you achieve the right results. Carrier Gas Flow 75 or 300 mL/min. MERCEM300Z: The mercury gas analyzer characterized by its very low mainte-nance requirements and long maintenance intervals. Principle of Operation of Direct Mercury analyzer DMA-80 Direct mercury analyser DMA-80is a dedicated technique used for quantification of mercury in different types of samples. In this work, operational conditions of a commercial thermal direct mercury analyzer (DMA-80 Milestone), which is normally used for total mercury determination, were investigated for performing mercury speciation. Description: The mercury analyzer is used to determine mercury concentrations in liquid and solid samples.The DMA-80 is based on the principles of sample thermal decomposition, mercury amalgamation and atomic absorption detection. Gasmet offers two solutions for Continuous Mercury Monitoring, the CMM and CMM AutoQAL. A direct mercury analyzer (DMA-80) was used to perform total mercury analysis and chemical speciation of mercury in water samples. Solid sample is combusted at high temperature (850 C) in the presence of interference-reducing reagents, releasing mercury from the matrix as reduced gaseous mercury. Measuring principle. Heating Temperature Approximately 600 °C. Mercury analysis is a critical test process that requires specific standard. There the quantitative determination of mercury is obtained by measuring UV absorption at a wavelength of 254 nm. Since its introduction nearly 20 years ago, the RA-915 Plus was widely accepted as the most accurate and sensitive mercury analyzer on the market. Measuring Principle - cold vapor atomic absorption spectroscopy (CVAAS) First the mercury contained in the sample is stripped with an air stream and sucked into an optical cell made of fused silica. Direct Mercury Analyzer Milestone Srl. PSA continues to invest in its research programme to extend the benefits of its total systems approach to all customer segments in order to provide mercury speciation distribution as well as total mercury concentration. Summary This chapter discusses the purpose, principle of operation, specifications, and applications of mercury analyser.
