Abstract: The present disclosure relates to the determination of pesticides, e.g., polar pesticides, in a sample using chromatography. The present disclosure can provide direct analysis of polar pesticides, including anionic polar pesticides, using high performance liquid chromatography. The polar pesticides are sufficiently retained and resolved to allow for multiple polar pesticide determinations in a single analysis.
