007-FFAP is a nitroterephthalic acid modified polyethylene glycol (PEG) polymer. This bonded acidic phase is ideal for the analysis of aqueous solutions of free fatty acids as well as fatty acid methyl esters. As with the 007-CW (and BTR-CW) polyethylene glycol phases, 007-FFAP is not recommended for the analysis of silylating reagents.

007-FFAP, Acid-Modified Polyethylene Glycol (PEG) columns are available in all standard column I.D.'s and lengths. The film thickness ranges are noted in the chart below.
