Phenomenex has announced the expansion of its Zebron Inferno high-temperature GC column line, adding two mid-polarity columns.
The ZB-XLB-HT and ZB-35HT columns can withstand temperatures up to 400C, enabling analyses of compounds with high molecular weights and boiling points.
The Zebron Inferno non-metal columns are stable at high temperatures due to coating and binding technologies, providing long lifetime, low bleed and low activity.
They are suitable for analyses in environmental, food and beverage, pharmaceutical, toxicology and biofuels applications.
Standard fused-silica columns are not engineered to withstand temperatures above 380C and their polyimide coating begins to degrade, eventually becoming brittle and inflexible.
The Phenomenex Inferno columns are specially designed for high-temperature analysis, with more rugged stationary phases and coatings.
The ZB-XLB-HT Inferno column is stable up to 400C and provides selectivity for confirmation analyses.
This MS-certified column offers low activity and good peak shape for acidic and basic samples.
The ZB-XLB-HT proprietary phase is suitable for polychlorinated biphenyls (PCBs), pesticides, herbicides and many EPA methods.
The ZB-35HT is a 35 per cent phenyl/65 per cent dimethylpolysiloxane intermediate-polarity column that is stable up to 400C, enabling high molecular weight analysis.
It is particularly suited to trace analysis with bleed-sensitive detectors.
Applications include semi-volatile compounds, pesticides, drugs of abuse, pharmaceuticals, steroids and many EPA methods.
