  • Dioxins and Furans on the Equity-5

    Dioxins and furans are byproducts of several different industrial processes, including incineration and paper bleaching. The extreme toxicity of several of these compounds has made their analysis in environmental samples increasingly important. In this application, the 60m x 0.25mm ID x 0.25µm Equity-5 was used to separate all 17 of the 2,3,7,8-substituted PCDDs and PCDFs listed in US EPA ...
