title: Determination of 19 chlorophenols by packed-column gas chromatography.
abstract: The use of packed columns has been explored for the gas chromatographic separation and identification of all 19 chlorophenol congeners after acetylation. Numerous mixtures of polar or nonpolar packings with either of two commercial Bentone 34 mixtures were tested. A mixture of 5% OV-101, 1.75% Bentone 34 on Chrom W-HP (100/120) mixed with twice its weight of 3% OV-225 on 100/120 Supelcoport separated all 19 congeners.
