Zusammenfassung: | The invention relates to a method for measuring contents of multiple mycotoxins in fresh and raw milk samples. The method comprises the following steps: S1, extracting extracts of the mycotoxins from the fresh and raw milk samples; S2, carrying out liquid chromatographic separation on the extracts of the mycotoxins, so as to obtain elution fractions; S3, carrying out mass spectrum identification on the elution fractions by using a triple-quadrupole mass spectrometer, so as to determine the types and contents of the mycotoxins. After the method is adopted, the fourteen mycotoxins are fully extracted; compared with a single-quadrupole mass spectrometer, the triple-quadrupole mass spectrometer adopted by the method is higher in accuracy, so that a target compound is better separated from interference impurities; therefore, reliable and accurate data can be provided.
本发明涉及种测定生鲜乳样品中的多种霉菌毒素含量的方法,其包括以下步骤:S1:从所述生鲜乳样品中提取霉菌毒素提取物;S2:对所述霉菌毒素提取物进行液相色谱分离,得到洗脱级分;S3:使用三重四级杆质谱仪对所述洗脱级分进行质谱鉴定,确定霉菌毒素的种类和含量。本发明可充分提取14种霉菌毒素,并采用三重四 |
