High-performance liquid chromatography has, to date, only found limited applications in the analysis of sludges (aliphatic hydrocarbons, cationic and non-ionic surface active agents, carboxylic acids and cobalamin). [Pg.109]

High-performance liquid chromatographic separation with electrochemical detection may provide the best sensitivity for phenol quantification in biological samples. The use of gas chromatography with a flame ionization detector may be a more versatile method, if other non-ionic pollutants must be quantified. The advantages and disadvantages of different methods available for the quantification of phenol and metabolites in biological and environmental samples have been discussed by Tesarova and Packova(1983).
