Restek’s polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

• Convenient 2 m length is ideal for use as a secondary column in GCxGC analyses
• Most stable polyethylene glycol (PEG) phase available
• Rugged enough to withstand repeated water injections
• Temperature range: 40 to 260 °C
• Polar phase; Crossbond® polyethylene glycol

Because of the increased stability produced by the bonding process, Stabilwax® columns exhibit long column lifetime, even when programming repeatedly up to 260 °C. The bonding mechanism of the column also produces polar compound retention times that do not shift as is often observed on other wax-type columns. In addition, this bonding mechanism produces a column that can be rejuvenated by solvent washing. Stabilwax® columns are used for a wide range of compounds and matrices including: FAMEs, flavor compounds, essential oils, solvents, aromatics including xylene isomers, acrolein/acrylonitrile (EPA 603), and oxygenated compounds. Also used for purity testing of chemicals and analyzing impurities in water matrices and alcoholic beverages.
