摘要: 样品经乙腈提取,正已烷液-液萃取、固相萃取净化后,用反相液相色谱法同时测定动物组织中15种磺胺类药物残留。采用AgilentC18柱,乙腈-0.02%磷酸梯度洗脱,紫外268nm处检测,柱温30℃,流速1.0ml/min。加标回收率在80.3%~92.3%之间。15种磺胺都能得以有效分离,方法准确可靠。

Abstract: After being extracted by acetonitrile, cleaned by n-hexane liquid-liquid extraction and solid phase extration(SPE), fifteen sulphonamides residues in animal tissues could be separated on Agilent C18 column using acetonitrile - 0.02% H3PO4 with gradient elution as the mobile phase at a flow rate of 1.0 ml/min, and then simultaneously detected at 268 nm, the column temperature was at 30 ℃. The recovery rates of sample were in the range of 80.9%~92.3%, fifteen sulphonamides residues could be separated completely ,which proved to be accurate and reliable.
