Stabilwax®-DA Fused Silica Columns

Polar phase: Crossbond® acid-deactivated Carbowax®polyethylene glycol

The analysis of volatile free fatty acids has been difficult on common siloxane stationary phases because of analyte adsorption and low sample capacity. Although PEG stationary phases exhibit improved capacity and better selectivity for many free acids, peak tailing still can occur. Stabilwax®-DA is a bonded PEG stationary phase that has been specially deactivated to analyze acidic compounds. The resulting inertness significantly reduces adsorption and increases sample capacity of volatile-free acids, thereby improving peak shape. It also eliminates the need to derivatize free fatty acids from C1 to C20, which simplifies sample preparation.

• Application-specific columns for free (underivatized) acids, some inorganic acids.
• Resistant to oxidative damage.
• Temperature range: 40°C to 250°C.
• Equivalent to USP G25, G35 phases.
