A novel method for detection of glufosinate in maize samples
was developed by ion-pair reversed-phase liquid chromatography.
The optimisation of derivatisation conditions, mechanism of ion
exchange and the effect of different ion-exchange conditions on
separation efficiency were discussed. In this study, the optimisated
conditions were used for quicker and better determination of
glufosinate in the maize samples. The proposed method showed
good repeatability, low quantification level (0.02 mg kg1) and
excellent linearity for quantitative assay of glufosinate in maize
samples.
