Stabilwax®-MS Columns

The new Stabilwax®-MS Columns from Restek have features which include lower bleed than VF-WAXms, high thermal stability polyethyleneglycol (PEG) stationary phase as well as the ability to withstand repeated water injections with no phase loss or degradation.

The new Stabilwax®-MS column from Restek meets a GC-MS user’s challenges. The polar deactivated surface tightly binds the polyethylene glycol polymer to the fused silica tubing, resulting in a high maximum operating temperature (260 °C). This allows for faster elution of higher molecular weight compounds since the column can be taken to high temperatures. In addition, low bleed levels are ensured by strict quality testing that specifies maximum allowable bleed levels of 4.0 pA for 0.25 mm ID columns and 5.0 pA for 0.32 mm ID columns. When comparing actual bleed levels on a mass spectrometer, Stabilwax®-MS columns outperform the VF-WAXms column.

When tested at the 250 °C temperature limit of the VF-WAXms column, less bleed is seen on the Stabilwax®-MS column.

The low bleed level of the Stabilwax®-MS column makes it suitable for GC-MS analysis of a wide range of polar compounds and matrices including: FAMEs, flavor compounds, essential oils, solvents, aromatics (including xylene isomers), acrolein/ acrylonitrile, and oxygenated compounds. The Stabilwax®-MS column is also useful for purity testing of chemicals and analyzing impurities in water and alcoholic beverages. When methods require trace analysis, the highly polar, low-bleed Stabilwax®-MS column produces excellent results compared to conventional wax columns. Review the applications in this brochure and try a low-bleed Stabilwax®-MS column for yourself.
