A method of determining 96 kinds of chili products pesticide residues

The present invention discloses a method for measuring an amount of 96 kinds of a pesticide residues chili products, pesticide residues in the sample was extracted with 1% acetic acid in acetonitrile homogenization, extraction was respectively Florisil SPE column and purified ethylenediamine -N- propyl silane (PSA), bonded phase octadecylsilane (C18) purification matrix dispersion, gas chromatography mass spectrometry (GC-MS) detection Florisil column purification was concentrated pesticide residues 69, liquid chromatography - tandem mass spectrometry (LC -MS / MS) detection of 27 kinds of purification matrix dispersion liquid pesticides, are used to establish a standard matrix blank solution was diluted calibration standard curve, when using internal standard and quantified by GC / MS, LC-MS / MS detection using external standard the statutory amount. This average recovery was 70.7% - 118.6%, average relative standard deviation (RSD) is 3.2% ~ 11.4%, the detection limit was 0.13μg / kg ~ 28.2μg / kg, is simple, rapid, accurate and sensitive and reproducible advantages.
