  • Mercury monitoring for ocean cruises - Water and Wastewater

    Mercury monitoring for ocean cruises

    Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependabil...

  • Mercury monitoring for mercury flux measurement - Monitoring and Testing

    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the...

  • Mercury monitoring for aircraft research measurement - Monitoring and Testing

    Mercury monitoring for aircraft research measurement

    An examination of the literature shows that the Tekran 2537 is the choice for measurements of mercury aboard research aircraft. Several research groups in Europe and North America have used the Tekran 2537 on an aircraft platform for point source plume studies, free troposphere speciation characterization, vertical profiles, characterizing emission source regions and even the stratosphere (http://www.caribic-atmospheric.com/instrum/hg.html). Normally, the Tekran 2537 requires simple modifications for aircraft...

  • Mercury monitoring for measuring mercury content in hair - Monitoring and Testing

    Mercury monitoring for measuring mercury content in hair

    Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 26...

  • Mercury monitoring for isotopic abundance by the ICP-MS - Environmental

    Mercury monitoring for isotopic abundance by the ICP-MS

    Studies of real-world ecosystems are very complex. Mercury species inter-conversion as well as mercury deposition and evasion are constantly occurring. One technique to help sort out the processes is to trace reactions using natural Hg isotopes. Either by enriching a system with a particular isotope or determination of isotopic ratios as a technique of source identification, isotopes are a powerful tool for investigation. The 

    Mercury monitoring for measuring mercury speciation in air - Air and Climate

    Mercury monitoring for measuring mercury speciation in air

    Tekran offers the only completely integrated, automated system for measuring mercury speciation in air. The Tekran 2537, when coupled to the Model 1130 and Model 1135 provides a continuous record of gaseous elemental mercury, gaseous oxidized mercury and particle-bound mercury. Over the past 12 years, the Tekran 2537-1130-1135 system has been the most significant tool used to advance the understanding of the fate and transport of atmospheric mercury. See the 

  • Mercury monitoring for on-site remediation - Soil and Groundwater - Site Remediation

    Mercury monitoring for on-site remediation

    Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously.
