APPLICATION-SPECIFIC COLUMNS

Specially Deactivated

Basic Compounds Analysis

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

compounds, without analyte derivatization or column priming. For different selectiv-

ity of basic compounds, or higher oven temperatures, use an Rtx®-5 Amine column.

Stabilwax®-DB is a bonded stationary phase, but avoid rinsing these columns with

water or alcohols.
