DESCRIPTION
Stabilwax-DA Columns
Material: (fused silica)
Phase Information: polar phase; Crossbond acid-deactivated Carbowax polyethylene glycol—for acidic compounds
• Application-specific columns for free (underivatized) acids, some inorganic acids.
• Resistant to oxidative damage.
• Equivalent to USP G25, G35 phases.
Stabilwax-DA columns should not be rinsed with water.
Stabilwax-DA bonded polyethylene glycol has an acidic functionality incorporated into the polymer structure. This permits analysis of acidic compounds without derivatization, significantly reduces adsorption of acids, and increases sample capacity for volatile free acids. Stabilwax-DA columns last longer and give better peak shapes for high molecular weight acids.
Some inorganic acids also chromatograph well on a Stabilwax-DA column; the limitation is the volatility of the acidic compound.
