Matrix effect in analysis of pesticide residues in fruits and vegetables by high performance liquid chromatography with quadrupole-time of flight mass spectrometry

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 commonly used methods of gas and liquid chromatography with time-of-flight mass-spectrometric detection.This system allows to carry out quantitative determination several hund

A Legendre spectral method based on a hybrid format and its error estimation for fourth-order eigenvalue problems

In this paper, we developed and studied an efficient Legendre spectral method for fourth order eigenvalue problems with the boundary conditions of a simply supported plate.Initially, a new variational formulation based on a hybrid format and its discrete variational form were established.We then employed the spectral theory of complete Racing Frame
