In this work, a micro-plate chemiluminescence enzyme immunoassay by antibody-coated for the determination of aflatoxin B1 (AFB1) in agricultural products has been established. Aflatoxin B1 antibody (AFB1-Ab) was adsorbed physically on polystyrene micro-plate hole as solid phase antibody, which took place immunity-reaction between antigen and antibody with AFB1 standard solution or samples by direct...
An automated online gel permeation chromatography–gas chromatograph mass spectrometer (GPC–GC/MS) was developed for the rapid determination of residual pesticides in agricultural products. Pesticides were extracted from homogenized food samples with acetonitrile and decontaminated via the matrix solid-phase dispersion (MSPD) technique, using a primary secondary amine as sorbent prior to GPC–GC/MS...
