New Metal GC Columns Deliver Higher Reproducibility for Petrochemical Testing

Phenomenex (USA) introduces the Zebron^TM ZB-1XT SimDist - a metal GC column specially designed for simulated distillation analyses in petrochemical applications. The new column features Phenomenex’s unique Glass Infusion^TM technology, which ensures consistent phase coating and reproducibility. Zebron ZB-1XT SimDist are rugged and provide documented efficiency gains of up to 70 percent over other comparable metal columns on the market. Every column is individually tested to guarantee quality.

Simulated boiling point methods are commonly used in petrochemical analysis to determine the range of hydrocarbons in a sample. These high-temperature distillation methods require resolution greater than 2.0 of C50 and C52, posing a challenge for most columns used in this application. The new Zebron ZB-1XT SimDist column exhibits less than 3.5 percent loss in resolution after 90 hours at 430° C.

"Traditional metal GC columns used in these applications have exhibited uneven stationary phase bonding, which negatively affects performance and reproducibility," explained Kory Kelly, GC product manager for Phenomenex. "Our proprietary bonding technology ensures consistent quality and each of our new columns is tested individually, rather than in batches."
