Abstract A gas-liquid chromatographic (GLC) procedure is described for the identification of 32 substituted phenols including all 19 chlorophenols and the 11 U.S. Environmental Protection Agency consent decree phenols. This method involves a simple and reproducible derivatization step which forms stable phenol PFB ethers for which the electron capture detector is highly sensitive. GLC retention time data of the derivatives on 6 packed and fused silica capillary columns (FSCC) are reported. The detection limits of all chloro-, alkyl- and mono-nitrophenols studied are between 0.5 and 5 pg injected for an FSCC. The high resolution of these capillary columns makes this method isomer-specific. The derivatization procedure also eliminates the sensitivity, tailing, and resolution problems commonly encountered in other gas chromatographic methods on underivatized phenols.
