Phenomenex has introduced the Zebron ZB-1XT Simdist, a metal gas-chromatography column (GC) specially designed for simulated distillation analyses in petrochemical applications.
The column features Glass Infusion technology, which ensures consistent phase coating and reproducibility.
Zebron ZB-1XT Simdist are rugged and provide documented efficiency gains of up to 70 per cent over other comparable metal columns, the company said.
Each column is individually tested to guarantee reliability.
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 Zebron ZB-1XT Simdist column exhibits less than 3.5 per cent loss in resolution after 90 hours at 430C.
Kory Kelly, GC product manager at Phenomenex, said: 'Traditional metal GC columns used in these applications have exhibited uneven stationary phase bonding, which negatively affects performance and reproducibility.
'Our proprietary bonding technology ensures consistent quality and each of our new columns is tested individually, rather than in batches.'
