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.

Abstract The normal phase and reverse phase liquid chromatographic properties of seven 8-quinolinesulfonyl derivatives of primary and secondary amines are examined using dual wavelength ultraviolet detection. The amines are further identified by infrared spectrophotometry with emphasis on structural elucidation based on absorption bands at characteristic wavelengths.
