Capillary electrophoresis and herbicide analysis: Present and future perspectives

Abstract

The aim of this article is to provide an overview on the potential of the CE-herbicides binomial. To this end, the methods proposed so far are discussed: their characteristics, types of samples and analytes to which the methods have been applied, sample preparation steps, if required (e.g. cleanup-preconcentration, derivatization steps), and type of detection in each case. Also, the methods are compared with counterparts based on LC, when appropriate. The role of MS detection in present and future analytical research in this field (both for identification and quantitation) are commented. The foreseeable and desirable trends in analysis of herbicides are also outlined in the light of the present trends in metabolomics as a way of knowing the pathways, the intermediate and final degradation products that can influence the crops and the food chain of humans and other animals, as a result.

Recent advances in the application of capillary electromigration methods for food analysis and Foodomics

“…Regarding the new developments of CE‐based methods for the analysis of this chemically diverse group of compounds, the bulk of published papers have been focused on herbicides. On this topic, a comprehensive overview of the current CE developments for herbicide analysis and a more general article reviewing the analysis of orphan and difficult pesticides have been recently published. Improvements in sampling and sample preparation methods used to detect herbicides in food products continue to be a high priority in this analytical area.…”

Separation and analysis of triazine herbcide residues by capillary electrophoresis

“…There are several excellent reviews dealing with the various aspects of pesticide separation in various matrices using CE (Dinelli et al , ; El Rassi, ; Karcher and El Rassi ; Martínez et al , , ; Eash and Bushway, ; Menzinger et al , ; Malik and Faubel, ; Pico et al , ; Hernández‐Borges et al , ; Rojano‐Delgado and de Castro MD, ). However, the analysis of triazine herbicides by the CE technique has not been reviewed.…”

Development of a capillary zone electrophoresis method to determine natamycin in food and a comparison with a liquid chromatography method

“…Compared with CE, HPLC method consumes a large amount of organic reagent, and usually requires a long analysis time. 27 In this study a convenient and efficient capillary zone electrophoresis (CZE) method was established to determine natamycin in food. The method is easy to operate, with a short analysis time and low reagent consumption.…”
