Mercury Ultratracer UT-3000 for measuring mercury in gases - 1

Mercury Ultratracer UT-3000 AIR QUALITY MONITORING The UT-3000 Mercury Ultratracer is a compact and reliable instrument for measuring mercury in gases at ultra trace levels according to the EN 15852. Utilizing the high performance GoldTrap amalgamation module and an optimized state-of-the-art AAmercury vapor detector the UT-3000 Ultratracer offers detection limits at sub-ng/m3 (ppt - parts per trillion) levels. SPECIFIC FEATURES: Measuring of Total Gaseous Mercury (TGM) in air and other gases such as natural gas, hydrogen, etc. at ultra trace levels Well proven detection method: Cold Vapor Atomic Absorption Spectrometry (CVAAS) Preconcentration of mercury using the proprietary Mercury Instruments GoldTrap Detection limit at sub-ng/m3 level, far superior to other instruments on the market Offers excellent long-term stability of measurement No need for a long optical cell thanks to enhanced sensitivity of the UV-detector in the UT-3000 High frequency driven electrode-less mercury low pressure lamp as UV light source provides high sensitivity, precision and stability Contrary to the ﬂuorescence detection method, the UT-3000 does not require expensive carrier gases Insensitive to interferences caused by the quenching effect The UT-3000 offers sensitivity and detection limits superior to other mercury analyzers on the market using similar technologies MAIN APPLICATIONS: Continuous outdoor and indoor air quality monitoring Stationary and mobile AQMS laboratories Industrial fence-line and ﬁeld monitoring Environmental pollution source tracking Studies of mercury dispersion in the atmosphere Mercury monitoring in natural gas or liqueﬁed natural gas (LNG) for quality control UT-3000 and the specially designed calibration unit AutoCal (option) Measurement Campaigns and Monitoring Studies

Mercury Ultratracer UT-3000 for measuring mercury in gases - 2

The Mercury GoldTrap is a key component of the measuring system. It consists of a wafer-thin ceramic tube with minimum thermal inertia located inside a protective cylinder. Ultra pure, solid gold is used as collecting medium. UT-3000 ﬂow diagram Optical cell The GoldTrap captures the total gaseous mercury (TGM) directly from the gas phase (gold amalgamation). After this accumulation phase the GoldTrap is heated up quickly. The adsorbed mercury is released suddenly (thermal desorption) in gaseous form and swept by an air stream into the optical cell of the detector. The mercury content is...
