Abstract: | The high-throughput analytical approach proposed for the assay of rotenone in lake and river waters presented here is based on atmospheric pressure chemical ionization (APCI) multiple-reaction monitoring (MRM) methodology whereby the analyte and internal standard solutions are directly analyzed, without any previous chromatographic separation. The very good accuracy is obtained by the critical choice of a reference compound that shows gas-phase chemistry similar to that of the analyte, by producing the same product ions selected for the MRM-based assay. |
