It could control the volume and speed of pulling and pushing cycles accurately. In this study, m-PFC was based on multiwalled carbon nanotubes (MWCNTs) mixed with primary-secondary amines (PSA) and anhydrous magnesium sulfate (MgSO4) in a packed column for analysis of pesticide residues followed by gas chromatography-mass spectrometry (GC-MS) detection. It was validated by analyzing 33 pesticides in kiwi fruit and kiwi juice matrices spiked at two concentration levels of 10 and 100 &mu;g\/kg.<\/p>\n<p style=\"text-align:justify\">Salts, sorbents, m-PFC procedure, 4 mL of automated pulling and pushing volume, 6 mL\/min automated pulling speed, and 8 mL\/min pushing speed were optimized for each matrix. After optimization, spike recoveries were within 71-120% and &lt;20% RSD for all analytes in kiwi fruit and kiwi juice. Matrix-matched calibrations were performed with the coefficients of determination &gt;0.99 between concentration levels of 10 and 1000 &mu;g\/kg. The developed method was successfully applied to the determination of pesticide residues in market samples.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-21917","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Beijing Advanced Innovation Center for
