| Abstract | The goal of this research effort was to develop instrumentation for the direct determination of total chlorinated organic compounds in aqueous samples without preconcentration. Two general approaches were investigated. The first involved isolation of the chlorinated organics from the sample matrix by flash evaporation. A catalytic conversion step was to produce free chlorine which was to be detected and quantified fluorometrically. This approach did not prove successful. An alternate procedure was investigated which used a piezoelectric crystal as the detection device. After evaluating a number of crystal coatings, Amine 220 was found to have appropriate characteristics. |
