The Elite-WAX ETR (Extended Temperature Range) columns are manufactured with a special bonding process that binds the Carbowax® polymer to the polar deactivated silica. This results in a low bleed WAX column that exhibits extended lifetimes even when repeatedly heated to 260 °C. The bonding mechanism results in very stable polar retention that does not shift as often as observed with other WAX-type columns. This phase can be used for a wide range of compounds and matrices such as: FAMEs, flavor compounds, essential oils, solvents, aromatics, acrolein/acrylonitrile, impurities in water and alcoholic beverages.
