The world’s leading manufacturer of advanced systems for laboratory, ambient air, petroleum, point-source mercury monitoring, and methyl mercury analysis. With pioneering expertise in cold vapor atomic fluorescence detection, Tekran® continues to expand and refine products for measurement of ultra-trace mercury levels. Tekran’s® ambient air instruments have been used on every ocean and continent, even Antarctica. The Tekran® Model 2537 Ambient Air Mercury Monitor was the first product developed by Tekran® and remains a driving force of innovation. The Model 2537 is the only analyzer available that is capable of automated, continuous, unattended atmospheric mercury speciation that offers determination of particulate-bound Hg, Gaseous oxidized Hg and Hg° species. Our instruments produce high-resolution, accurate data that continues to advance the understanding of mercury cycling in the environment. Tekran® ambient air analyzers have been chosen by monitoring networks in the USA (NADP-AMNet), Canada (CAPMoN), Europe (EMEP) and in many other countries such as Korea, China, Germany, Poland and South Africa, to name but a few. As a testament to our excellence, our analyzers have set the standard for ambient air monitoring with hundreds of installations throughout the globe. Tekran® 2537X Automated Ambient Air Analyzer has become the worldwide standard for ambient air mercury measurement. The combination of our patented dual pure-gold cartridges and ultra-stable CVAFS detector provide unmatched accuracy sensitivity and reliability. The Tekran® 2537X has opened up a wide array of applications that have been published in peer reviewed scientific journals.
