| Tartalmi kivonat: | Examples for determination of surfactants used in agrochemicals will be presented by using different instrumental analytical methods. Liquid chromatography coupled to mass spectrometry (LC-MS) is more convenient for characterization of these mixtures compared to gas chromatographic (GC) methods. However, due to better separation of GC it allows more detailed information about the composition of the mixtures analysed, but usually prior to GC derivatisation is required. Two chemical modifications for GC-MS measurements were investigated in detail: conversion of sulfonates to trifluoroacyl esters as well as silylation of hydroxy compounds. |
