Abstract

A method for extracting organic substances from aqueous media by combining extraction with freezing is described. The method allows hydrophilic extractants to be used. Analysis of ionogenic organic compounds provides an example demonstrating the wide potential of this method. A method for the analysis of 1,4-benzodiazepines in urine was developed. As compared with existing methods, the sample preparation procedure described here is significantly quicker and simpler, and requires virtually no laboratory equipment.
