Introducing the new Tekran 3300Xi HgCEM. The Tekran 3300Xi is modular, simpler to install and maintain, includes the new Tekran 2537Xi detector and is operated with updated CEM+ software (Tekran 3321Xi pictured). The 3300Xi is the ideal platform for inlet/outlet control technology optimization, regulatory monitoring of mercury emissions and bench-scale laboratory research.

The Tekran 2600-IVS has been smartly reconfigured for direct in-vial sparging sample introduction. The 2600-IVS requires less hardware components to reduce initial purchase cost. More importantly, daily operation costs are dramatically reduced by elimination of consumables, reagents and waste. The 2600-IVS also offers better throughput with greater than 25% reduction in sample process time.

Tekran provides trace-level mercury analytical and monitoring technology for a variety of applications including laboratory-based sample analysis, continuous point-source emissions and ambient air monitoring. This article focuses on and highlights the results of an application of Tekran’s Ambient Air Mercury Speciation System.
In contrast to most other heavy metals, mercury (Hg) and mercury compounds in the environment exhibit exceptional behaviors including methylation, volatilization and biomagnification. Since mercury is a potent neurotoxin, it is the latter which has spawned particular interest in understanding its production,
transport, speciation and fate.
Mercury is emitted into the atmosphere from natural (e.g. volcanic activity) as well as anthropogenic sources (e.g. combustion processes). It is generally accepted that anthropogenic sources of mercury have surpassed natural sources; a trend which may continue with the world-wide increase in coal burning for electric power generating units. Thus, the incentives for additional measurements of atmospheric mercury and the attendant understanding of its transport, conversion and fate, are clear.
Using Tekran’s Model 2537 and speciation modules 1130 and 1135, American and Canadian researchers have determined that there are exceptionally high levels of gaseous oxidized mercury (a.k.a. RGM) and particulate-bound mercury in the Arctic. A synthesis of Arctic atmospheric mercury speciation measurements made in 5 countries and the linkages to snow and water has recently been summarized. Analogous research at the German Antarctic Station, Neumayer, has revealed similar patterns, including mercury depletion events (MDE’s) after polar sunrise. The German researchers in this program enhanced their study by using the Tekran Ambient Air Mercury Speciation System aboard a research ship near Antarctica.
Just recently, compelling gaseous elemental mercury (GEM) measurements at Cape Point, South Africa were reported for the years 2007 to 2008. The Cape Point observations revealed large MDE’s at a location outside of the polar region. Also observed were pollution events that were attributed to biomass burning and industrial emissions. The article goes on to explain the observations taking into account the chemistry of the marine boundary layer and transport from the continent. One specific conclusion suggests that the residence time of GEM in the marine boundary layer could be much shorter than current estimates.

The Global Mercury Observatory System (GMOS) is a 5-year project funded by the European Commission to establish a world-wide system for the measurement of atmospheric mercury in ambient air and precipitation samples. There are numerous “Partners” in GMOS from many countries. The coordination of the project is being done by the CNR Institute of Atmospheric Pollution Research in Rome.
The GMOS program relies heavily on the Tekran 2537B Automated Mercury Monitor coupled with the Tekran 1130 and Tekran 1135 modules to measure air mercury speciation at ground based locations and during ocean cruises. In order to support GMOS, Tekran staff helped to organize and conduct a 3-day training session on the Tekran 2537-1130-1135 Atmospheric Mercury Speciation System at the CNR site in Rome. Tekran was joined by and worked side-by-side with Mark Olson of the North American Atmospheric Mercury Network (AMNet). There is a productive collaboration between AMNet and GMOS. There were 25 attendees in all from countries such as South Africa, Cape Verde, Argentina and Suriname to name a few.

More mercury is deposited in the Arctic than anywhere else on the planet. NTNU researchers think one explanation for this may lie in the meteorological conditions in the Arctic spring and summer.
The concentration of mercury in humans and animals that live in polar regions is on the increase. Polar bears and humans that eat marine mammals are the most affected. But why is there more mercury in the Arctic than elsewhere?
Scientists have been puzzling over this question since the beginning of the 1990s. Their first breakthrough came when it was discovered that under certain meteorological conditions, mercury from the air is deposited on the snow and ice in polar areas. The phenomenon occurs when the sun rises over the horizon in the spring, after a long polar night.
Now new research from NTNU PhD candidate Anne Steen Orderdalen and Professor Torunn Berg at the Department of Chemistry and the Norwegian Institute for Air Research (NILU) shows that this process also occurs in the summer as well as in the spring. In a series of publications, the researchers have documented the types of mercury found over the Arctic and are tracking its fate and transport. Essentially, far more mercury is deposited in the Arctic than initially thought, which may be due to the extended time period during which it can be transformed and deposited. Scientists still don’t know exactly why and how the process occurs. But sunlight appears to be an important factor. Read More

The International Conference on Mercury as a Global Pollutant is right around the corner and starts July 24th? With the conference returning to Canada for the first time since 1994, Tekran will be letting our Canadian pride show. As a Quicksilver Sponsor, Tekran has given our financial support in recognition of the ICMGP as the pre-eminent gathering of mercury researchers and policy makers. Tekran is also sponsoring the Maritime Kitchen Party on Tuesday evening to provide time to catch up with colleagues in an informal setting as well as entertain all.
Tekran is offering an Advanced Users Course for our current and future atmospheric mercury speciation scientists and technicians. The short course will be especially useful to the established and newly developed atmospheric mercury speciation networks such as CAPMoN, AMNet, and GMOS. Traditionally, Tekran often brings newly developed instrumentation to the ICMGP conference to exhibit for the first time. Perhaps this year will be no exception . . . come by our booth and see for yourself.
