Tekran® is an international leader in environmental measurement technology, serving the needs of industry, government and research institutions with applications ranging from pure research to primary manufacturing. We revolutionized continuous mercury monitoring through the use of cold vapor atomic fluorescence spectrophotometry and pure gold pre-concentration. Tekran’s systems for ultra-trace measurement of mercury in ambient air, stack emissions, and environmental samples are extraordinarily sensitive and robust with detection limits of less than 1 picogram absolute and practical immunity to interfering compounds.
