Measurement of Total Gaseous Mercury in Air or Other Gases at Ultratrace Levels The UT-3000 Mercury UltraTracer provides a compact and reliable tool for measuring mercury in gases at ultra trace levels. Utilizing the high performance GoldTrap amalgamation module and an optimized state-of-the-art AA-mercury vapor detector the UT-3000 UltraTracer offers detection limits at sub-ng/m3 (ppq-parts per quadrillion) levels. Mercury Monitoring in Natural Gas and LNG Mercury is a frequent constituent of natural gas. It can be found in concentrations from a few µg/m³ up to >10000 µg/m³. An important application for the UT-3000 is the measurement of mercury in natural gas and liquefied natural gas (LNG). A special version of the UT-3000 analyser is dedicated for measurement of mercury in natural gas. Both a manual system using the Tedlar® Bag Technique as well as an automatic system for on-line installations are available. Automatic operation The UT-3000 operates automatically. Are functions are controlled by an embeddedmicroprocessor. Once the analysis has been started, measurements are performed and data is collected by the buil-in datalogger. With standard settings the datalogger has a recording capacity of 4 weeks. Gold Trap Amalgamation System For use in the UT-3000 a new trapping system has been developed: the Mercury Gold Trap, which is one of the key components of the system. It consists of a wafer thin ceramic tubewhich has been carefully crafted to achieve minimum thermal inertia. The tube has been packed with ultrapure gold and supports a heating coil on its outside. The Mercury Gold Trap reveals sharp and high peaks and a excellent long-term stability. As air is used for purging the the trap during the heating step, possible contaminats are oxidized and swept off thus preventing passivation.
