“…The filtration of extracts before injection onto chromatographic column avoids rapid obstruction of the precolumn, increasing its life. The main advantage of this method in comparison with previous papers report in literature [28,29] is the rapid SPE procedure for the preparation of the biological sample, which gives high extraction yields. The proposed HPLC method employing solid-phase extraction for sample preparation is simple and convenient for the determination of iprodione and vinclozolin in urine samples.…”
