ABSTRACT
A novel HPLC-CAD method coupled with on-line solid phase extraction ( SPE ) for the determination of erythrocin which was widely used in livestock farming was developed. After mixed with diatomite, 5. 0 g manure sample was put into the cell and extracted with hot water at 70℃ and 10. 3 MPa. An on-line SPE methodology was applied to pre-treat the sample, and the sample was seperated on an Acclaim 120 C18 column and analyzed by corona CAD detector using acetonitrile and 0. 1% formic acid as mobile phase. Good linearity for erythrocin was obtained in the range of 21-2000 μg/kg. The detection limit was 6. 3 μg/kg. The average recoveries were 79. 2%-87. 5%.
