Product/Service Name: Flett Research Ltd. Company: Flett Research Ltd. is an environmental laboratory and consulting firm in Winnipeg, Manitoba, Canada. Founded in 1978 by Dr. Robert Flett (PhD) ; 440 De Salaberry Avenue ; Ph: (204) 667-2505 Welcome to the Flett Research Home Page. Flett Research Ltd. is an environmental laboratory and consulting firm in Winnipeg, Manitoba, Canada. Founded in 1978 by Dr. Robert Flett (PhD), the company specializes in the analysis of mercury and environmental radioisotopes. We have supplied services to clients from North and South America, Europe and Asia. Our specialized clean lab and highly sensitive equipment allow us to analyze ultratrace levels of mercury (Hg), including both total and methyl mercury, in a wide array of environmental samples (water, sediments, tissues, air etc.). For example, in 100 mL of water, our detection limit is ~ 0.1 ng/L for total mercury and ~ 0.02 ng/L for methyl mercury. Please refer to our Mercury Page for more information on Flett Research's mercury analyses, including the type of mercury analyses performed, analytical prices, quantitation limits, and a brief write-up on our analytical capabilities and methods. Lead-210 ( Pb-210 ) and cesium-137 ( Cs-137 ) are the environmental radioisotopes that we analyze most frequently, primarily for the purpose of dating sediment cores. The dating of sediment cores by the Pb-210 method can be used to determine the sediment accumulation rate for a body of water and the age of the sediments at a particular depth can be inferred. The age of sediments at different depths can be used to document historical contamination. Beryllium-7 ( Be-7 ) is also measured for clients wishing to know if a sediment is recent i.e. deposited less than 1 year before sampling. For information on the environmental radioisotope analyses available at Flett Research Ltd., please refer to our Environmental Radioisotope Page. To learn how Pb-210 is used in the dating of sediment cores please refer to our page on Understanding the Pb-210 Method. |
