The Tekran^® 2537X is easy to setup, use, and maintain and is known for its stable performance in rugged conditions – installed at both Polar Regions, on ocean research vessels and hundreds of locations in between. As a testament to the longevity of our products, the first Tekran^® 2537X analyzers produced are still running strong and producing quality data with over 15 years of continuous operation.

While the Tekran^® 2537X is typically tasked with continuous ambient air monitoring, other applications are easy to achieve. For example, by continuously measuring the inlet and outlet of a flux chamber, the exceptional sensitivity of the 2537X can be used to determine differential surface emission and deposition rates. The 2537X is most often used with the model 1130 and 1135 to continuously measure atmospheric mercury speciation. The 2537X has also been applied to study and monitor mercury control technology, dissolved gaseous mercury, surface flux by gradient techniques, indoor air, plume chemistry, free-tropospheric air and point sources impacts, to name but a few. In cases where higher air concentrations are expected, the Tekran^® 2537X can be purchased in an alternate configuration to extend the upper range of the analyzer. This is useful for industrial monitoring and site remediation projects where mercury concentrations are expected to far exceed the typical ambient air concentrations.

Measurement of GOM with the Tekran^® Model 1130 is the important link connecting deposition of air mercury to sensitive aquatic ecosystems. Emissions of GOM from point sources, in-situ production and transport can result in locally enhanced mercury deposition. Thus air speciation of mercury is of particular interest close to industrial sources. Over 100 peer-reviewed articles have been published featuring data generated by the Tekran^® Model 1130 at field sites throughout the world. The Tekran^® 2537-1130-1135 Atmospheric Mercury Speciation System has been chosen by networks around the world, including the, Canadian-CAPMoN, NADP AMNet, EU EMEP, Korea-NIER, Chinese Academy of Sciences and others around the world.

The majority of atmospheric mercury is present in elemental form, but differentiation is important due to the greater local impact of reactive (ionic) forms. The Model 1130 provides a supplemental pump system to minimise sample collection periods, and produce mercury-free air for use during analytical cycles.

Key Features:

• Integrates seamlessly with the Tekran^® 2537 Analyzer
• Separate controller allows sensitive components to be indoors
• Adsorbing surface is regenerated with each desorption cycle
• Data logging option captures flows and temperatures.

The complete Tekran® 2537-1130-1135 Atmospheric Mercury Speciation System provides fully automated, unattended operation to determine all three mercury species concurrently. It is the only system available which has this advanced capability to routinely measure part per quadrillion mercury speciation in ambient air.

Measurement of Hgp with the Tekran® Model 1135 is the important link connecting deposition of air mercury to sensitive aquatic ecosystems. Emissions of Hgp from point sources, in-situ production and transport can result in locally enhanced mercury deposition. Thus, air speciation of mercury is of particular interest close to industrial sources.

Networks around the world have chosen the Tekran® 1135 for mercury speciation monitoring in air.

Conventional particulate sampling is not successful at separating mercury species since GOM has a high affinity for surfaces and sticks to filter media, biasing results. The Tekran® 1130 – 1135 Modules solve this problem by selectively capturing the GOM fraction from the sampled air stream prior to the Model 1135 particulate mercury filter element. Analysis occurs by heating and pyrolysis to release the HgP as GEM for detection and thermally decomposing the particulate matter. Enhanced instrument status and performance is monitored using Tekran® DataCom software, providing the operator with continuous quality assurance results.

Features:

• Connects directly on top of 1130 – no additional mounting is required
• Particulate filter is regenerated with each desorption cycle
• Data logging option captures flows and temperatures
