Metal MXT® Columns
Rugged, flexible, Siltek®-treated stainless
steel tubing; inertness comparable to
fused silica tubing.
MXT®-WAX columns............
Stabilwax® Columns (fused silica)
(polar phase; Crossbond® polyethylene glycol)
• Rugged enough to withstand repeated water injections.
• Low-bleed PEG column ensures long column lifetimes.
• Temperature range: 40 °C to 260 °C.
• Equivalent to USP G14, G15, G16, G20, and G39 phases.
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, es-
sential oils, solvents, aromatics (including xylene isomers), acrolein/acrylonitrile (EPA
603), and oxygenated compounds. Also used for purity testing of chemicals and ana-
lyzing impurities in water matrices and alcoholic beverages.
