Abstract
Analysis of the pyrethroid Deltamethrin in mint oil was achieved at 10 ng g (-1) level by off-line coupling liquid chromatography (HPLC) and capillary gas chromatography (CGC). Both LC and GC conditions are discussed. Mass spe ctrometry (MS) was used as detection system for the gas chromatographic ana lysis, The single ion monitoring (SIM) mode was chosen, in order to enhance on selectivity and sensitivity. Simultaneous monitoring of three mass chan nels and calculation of the respective intensity ratios allows structural c onfirmation. Attempts for replacing the LC fractionation step by SPE fail.
