Abstract:A GC-FID method was developed to determine the content of 1,2-dichloroethane in technical trifloxystrobin. In this method, the sample was dissolve in dichloromethane and separated by an Agilent DB-FFAP capillary column. A linear relation (r=0.997 1) and a satisfied precision results (SD=5.08 mg/kg, RSD=2.52%) along with an average recovery of 95.5% and the LOQ of 96 mg/kg were obtained. This method is suitable for the analysis of 1,2-dichloroethane in technical trifloxystrobin with high selectivity, accuracy and efficiency.
Key words:1,2-dichloroethane; technical trifloxystrobin; GC; external standard method
