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.
Stabilwax-DA columns should not be rinsed with water.
