Analysis of chlorfenapyr·chlorantraniliprole 30%SC by HPLC
An analytical method of chlorfenapyr·chlorantraniliprole 30%SC was established by HPLC.Chlorfenapyr and chlorantraniliprole were determined on stainless steel column C i8,using methanol+water(volume ratio of 80∶20)as the mobile phase,at the wavelength of 254 nm.The results showed that the linear correlation coefficients of chlorfenapyr and chlorantraniliprole were 0.999 5 and 0.999 2,the standard deviations were 0.02 and 0.02,the relative standard deviations were 0.1%and 0.2%,and the average recoveries were 99.64%and 99.31%,respectively.The method was simple and rapid,with high accuracy and precision,good linear correlation.It could be used for the quantitative analysis of chlorfenapyr and chlorantraniliprole in compound products.
