Stabilwax®-DB Columns
(fused silica)
(polar phase; Crossbond® base-deactivated Carbowax® polyethylene glycol—for amines and
basic compounds)
• Application-specific columns for underivatized amines and other basic compounds,
including alkylamines, diamines, triamines, nitrogen-containing heterocyclics. No
need for column priming.
• Temperature range: 40 °C to 220 °C.
Stabilwax®-DB columns reduce adsorption and improve responses for many basic com
pounds, without analyte derivatization or column priming. For different selectivity o
basic compounds, or higher oven temperatures, use an Rtx®-5 Amine column.
Stabilwax®-DB is a bonded stationary phase, but avoid rinsing these columns wit
water or alcohols.
