摘要

建立了蜂蜜中农药残留的快速液相色谱-质谱联用测定方法。为此，对QuECHERS方法进行了不同的变化：（i）样品的量，（ii）控制pH的盐的类型，（iii）缓冲液的pH，以及（iv）用于清洁的不同混合物。此外，为了证明该方法是可靠的，研究了不同的验证参数：准确度、检测和定量限、线性和选择性。结果表明，通过引入的变化，可以获得一种更具选择性的方法，提高从原始方法中选择的约19种农药的准确性。结果表明，该方法适用于56种农药中的50种农药的分析。此外，采用所开发的方法，回收率在70%至120%之间，相对标准偏差低于15%。

Desarrollo y validación de un método multiresiduo para el análisis de plaguicidas en miel por UFLC-MS

A method for the determination of pesticide residues in honey by ultra fast liquid chromatography coupled with mass spectrometry was developed. For this purpose, different variations of the QuECHERS method were performed: (i) amount of sample, (ii) type of salt to control pH, (iii) buffer pH, and (iv) different mixtures for cleaning-up. In addition, to demonstrate that the method is reliable, different validation parameters were studied: accuracy, limits of detection and quantification, linearity and selectivity. The results showed that by means of the changes introduced it was possible to get a more selective method that improves the accuracy of about 19 pesticides selected from the original method. It was found that the method is suitable for the analysis of 50 pesticides, out of 56. Furthermore, with the developed method recoveries between 70 and 120% and relative standard deviation below 15% were found.
