A comparison has been made of a silica and an alumina column with respect to retention behaviour in high-performance liquid chromatography of pure drug solutions and plasma profiles following on-line solid-phase extraction. Using methanol-ammonium nitrate buffer (80:20, v/v) as eluent, it was found
repeated runs on one single capillary column. This is illustrated in the analysisofa realsample (Figure I), onacapillarycolumnwhich had taken more than 50 samples.The quantitative resultobtained, 7 ppm of Arochlor 1260, was confirmed by official Government Laboratories. ## Figure 1 Waste oil cont
