Analysis of Imidacloprid · Novaluron 18％ SC by HPLC-MS/MS
[Aims] The aims were to establish a HPLC-MS/MS method to detect the imidacloprid · novaluron 18％ suspension agent.[Methods] The separation and quantitative analysis of imidacloprid and novaluronin the samples were conducted by HPLC-MS/MS and MSD detector with the mixture of 2 mmol/L ammonium acetate solution and acetonitfile (within 0.1％ formic) (25:75,by vol) as mobile phase and with ZORBAX SB-C18 column as fix phase.[Results] The results showed that the linear correlation coefficients for imidacloprid and novaluron were 0.9996 and 0.9999,the variation coefficients were l.14 and 5.50％,the average recovery rates were 88.21 and 79.78％,respectively.[Conclusions] The method is simple,the accuracy,precision and sensitivity can meet the requirement,which is suitable for analysis of imidacloprid · novaluron 18％ suspension agent.
