By switching to the unique selectivity of ZB-Dioxin you will gain enhanced resolution of 2,3,7,8-TCDD and 2,3,7,8-TCDF from its isomers in one run, and only need a single ZB-Dioxin GC column as your SINGLE column solution for Dioxin analysis. Upgrade your existing GC column for Dioxin analysis to a Zebron ZB-Dioxin GC column and get all the analytical benefits and productivity gains of a single column solution.

SecurityGuard offers a convenient and economical way to extend HPLC column lifetimes. Did you know a common cause of high backpressure, split peaks, broad peaks, baseline noise, baseline drift and loss of resolution is contaminants? The fact is all mobile phases contain some chemical contaminants or microparticulates, from the sample, solvent, or wear on the polymeric seals of the pump or injector. These contaminants can…
