Restek’s polar-deactivated surface tightly binds the Carbowax polymer and increases thermal stability, relative to competitive columns. Because of the increased stability produced by the bonding process, Stabilwax columns exhibit long column lifetimes, 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 alcoholic beverages.
