✦ Synopsis

Flophemesyl (pentatluorophenyldimethylsilyl) derivatives of alcohols, phenols, carboxylic acids and amines have been prepared and their suitability for determining trace amounts of these compounds by _gx chromatography assessed. They are very sensitive to electron-capture detection (ECD) down to the picogram to femtogram range and have advantages over presently used ECD derivatives particularly for lower-molecular-weight compounds.

## Abstract A method is presented for the simultaneous determination of a wide range of carboxylic acids and phenols in water. Extractive alkylation is used with the tetrabutylammonium ion as counter ion and pentafluorobenzylbromide as alkylating agent. Extracts are analyzed by glass capillary gas
