Zebron GC Columns Enable Faster Separation

100% Aqueous Stability for Polar Compounds100% aqueous stable, excellent for aqueous samples; bonded and solvent rinseableExtremely inert for acidic compoundsEnhanced selectivity for low boiling solvents; high retention of alcohols and chlorinated solventsIncreased efficiency at 20 °CZB-WAXplus provides optimal selectivity for many aqueous soluble compounds such as those found in alcoholic beverages or glycol samples. The ZB-WAXplus bonding process results in exceptional stability to repeated injections of aqueous matrices like whiskey. Multiple or routine water injections will not alter the efficiency or polarity of the phase over time.Recommended UseAlcohols, Aldehydes, Aromatics, Essential Oils, Flavors & Fragrances, Free Fatty Acids, Glycols, OVIs, Pharmaceuticals, Solvents / Residual Solvents, Styrene, Xylene IsomersEnhanced Aqueous Stability

A New Generation of Performance for Semi-Volatiles AnalysisZB-SemiVolatiles delivers inert, rugged performance with Enviro-Inert™ Technology enhanced 5% phenyl-arylene selectivity. We take the guesswork out of meeting method requirements - troublesome compounds in your samples and the 8270D tuning standard are used as our QC mix, so you can be sure your column is ready to meet suitability requirements for the method!5 Reasons Chromatographers Love ItDelivers supreme inertness for acids, amines, and other notoriously active compoundsHold calibrations and increase productivity up to 58%Detect down to ultra-low levels (0.2 ng on-column)Improve critical pair resolution (valley height 9.9% for benzo[b] and benzo[k])The most popular choice for testing of semi-volatiles, PAHs, and PBDEsRecommended UseSemi-volatiles (SVOCs), PAHs, PBDEs, EPA Methods (525, 610, 625, 8100, 8270D)Specifically Designed for Supreme SVOC Inertness
