Zebron ZB WAXPLUS GC Column

WAX columns from different manufacturers are not always created equal!

As part of the Zebron PLUS GC column family, ZB-WAXPLUS is manufactured using improved technologies that reflect our attention to detail every aspect of a ZB-WAXPLUS column’s anatomy is meticulously engineered and individually tested for unprecedented performance.

Water Reproducibility of ZB-WAXPLUS

Historically, polyethylene glycol (PEG) phases have been unstable with aqueous samples such as beverages or glycols, resulting in poor reproducibility and decreased lifetime. The ZB-WAXplus bonding procedure results in exceptional stability to repeated injections of aqueous matrices.

ZB-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.
