GC Columns Bring High-Temp Stability to Mid-Polarity Analyses

Phenomenex’s Zebron Inferno high-temperature GC column line now includes two new mid-polarity columns. The ZB-XLB-HT and ZB-35HT can withstand temperatures up to 400 C, enabling analyses of compounds with high molecular weights and boiling points.

The non-metal columns are stable at high temperatures due to proprietary coating and binding technologies, providing a long lifetime, low bleed and low activity. They are suited for analyses in environmental, food and beverage, pharmaceutical, toxicology and biofuels applications.

The ZB-XLB-HT column provides unique selectivity for confirmational analyses. This MS-certified column offers low activity and good peak shape for acidic and basic samples. The ZB-XLB-HT proprietary phase is suited for polychlorinated biphenyls (PCBs), pesticides, herbicides and many EPA methods.

The ZB-35HT is a 35%-phenyl-65%-dimethylpolysiloxane intermediate-polarity column that enables high molecular weight analysis. It is particularly suited for trace analysis with bleed-sensitive detectors. Applications include semi-volatile compounds, pesticides, drugs of abuse, pharmaceuticals, steroids and many EPA methods.
