For modern food safety control are using techniques that allow to determinate a large number of components.So for determination of pesticide residues in fruits and vegetables Mens Hats commonly used methods of gas and liquid chromatography with time-of-flight mass-spectrometric detection.This system allows to carry out quantitative determination several hundreds of pesticides and their identification by the characteristic fragments of the mass spectrum.

The main problem when using mass spectrometric detection is a matrix effect, which is caused by the influence of matrix components extracted with pesticides from the sample.In this work, attempts have been made to reduce the influence of the matrix Low Air Loss Mattresses in the analysis of pesticide residues by high performance liquid chromatography with time of flight mass spectrometry (HPLC / TOFMS).
