It involves matrix solid-phase dispersion (MSPD) for preconcentration before rapid resolution liquid chromatography-tandem mass spectrometry (RRLC-MS-MS). In the MSPD pre-concentration step, the adsorptive performance of multi-walled carbon nanotubes (MWCNT) as MSPD adsorbent and elution with four solvents were investigated; in the LC separation step, a rapid resolution high-throughout LC column was used with gradient elution. The results of the research showed that the linear correlation coefficients (r 2) of the method for the nine target analytes varied between 0.9942 and 0.9996, mean recovery was in the range 71.2-102.8%, with relative standard deviations (RSD) 2.0-11.8%, and limits of detection were all below 0.2μgkg−1. The method was used for simultaneous analysis of the nine pesticides in eight different fruit and vegetable samples.
