Capillary columns, Stabilwax®-DA (fused silica)
Kromatografikolonner
Application specific columns for free (underivatized) acids and some inorganic acids. Resistant to oxidative damage.

Polar phase; Crossbond® acid deactivated Carbowax® polyethylene glycol for acidic compounds

Stabilwax®-DA bonded polyethylene glycol has an acidic functionality incorporated into the polymer structure. This permits analysis of acidic compounds without derivatisation, significantly reduces adsorption of acids and increases sample capacity for volatile free acids. These columns give better peak shapes for high molecular weight acids.

Temperature range: 40 to 260 °C

Similar phases: HP-FFAP, DB-FFAP, CP-WAX 58 FFAP CB, NUKOL, ZB-FFAP. Equivalent to USP G25, G35 phases.
