Product information "Restek Stabilwax GC capillary column (60 m, 0.32 mm ID, 1.00 µm), 10657"

The Restek Stabilwax (MPN 10657) is regarded as the de facto standard amongst polar wax columns and is characterised by its exceptional thermal stability within an otherwise sensitive class of stationary phases. Based on a cross-linked polyethylene glycol (PEG), this column utilises a proprietary polar-deactivated surface that binds the Carbowax polymer more firmly than conventional methods. The result is a ‘Crossbond’ phase that is not only mechanically robust against repeated water injections but also exhibits minimal column bleeding even under aggressive temperature programmes up to 260 °C.

Phase stability and reproducibility

For the chromatographer, the Stabilwax’s unique binding mechanism means one thing above all: consistent retention times. The ‘shifting’ of polar compounds often observed with wax phases is eliminated here. This makes the column the first choice for validated methods in FAME analysis, the determination of flavour compounds or the purity testing of solvents (e.g. xylene isomers), where retention time stability over weeks and months is critical.

Durability and regeneration

A key technical advantage of Crossbond technology is the possibility of regeneration. Should the separation performance decline due to non-volatile matrix residues, the Stabilwax can often be restored by solvent rinsing. It covers a wide range of applications, from the analysis of alcoholic beverages to critical environmental parameters such as acrolein/acrylonitrile (according to EPA 603), and offers equivalence to USP phases G14, G15, G16, G20 and G39.
