摘要：
An HPLC method for determination of cymiazole in honey using a narrow bore C-18 column is described. Preconcentration and sample cleaning were achieved by using solid-liquid extraction with SCX Bond Elut cartridges. The performance of UV and amperometric (EC) detector systems were also compared. The detection limits with UV and EC detectors were 1.7 and 0.7 mu g kg(-1) respectively. Average recoveries obtained with UV and EC detectors were 91.2% and 86.1% with a standard deviation of 3.8% and 12.5% respectively. In spite of its higher sensitivity the EC detector is not suitable for this type of analysis because of its lack of reproducibility and the long analysis time required.
