The Tekran® ambient air mercury speciation system has been taken to new heights. The Tekran® 2537-1130-1135 speciation system has been successfully deployed for long-term monitoring at an elevation of 3810 meters (12,500 ft) at Mt. Waliguan, China. This beats the old record of 2763 meters (9065 ft) at Mt. Bachelor set by Dr. Daniel Jaffe’s Research Group. The installation and ongoing operations at Mt. Waliguan, China is by Dr. Xinbin Feng’s Research Group at the State Key Lab, Chinese Academy of Sciences in Guiyang, China. Additional support and advisement for this high elevation site is being accomplished by Tekran China Representatives, Ample Technology Services and the Tekran R&D Group. Dr. Feng is one of the premier mercury scientists in China with a long list of important publications. Dr. Feng’s group operates 5 atmospheric mercury monitoring sites in China using Tekran® equipment. At this elevation, the Tekran® analyzer is able more clearly observe and better quantify long range transport events in the Asian troposphere. At such elevations, it is also possible to investigate the atmospheric chemistry of mercury unique to the free troposphere, which will better serve modelers.
