摘要 采用高效液相色谱法(HPLC)测定猪血浆中的CTC残留量。试验采用AgilentHP1100系统,Agilent ODSC18(150 mm×4.6×5)柱,流动相选用乙腈—0.01 mol/L草酸(3+2);检测波长为372 nm;进样量:50μL;柱温:室温。血浆样品经草酸提取后,过C18柱净化,该方法样品前处理简单,药物的线性关系好,相关系数达0.999 89。检测限为0.05μg/mL,平均回收率在75%以上,变异系数均<6.6%。该法前处理简便、灵敏度高、结果准确、可靠。 This experiment uses (HPLC) to determine the chlortetracycline residues amount in the pig plasma. The experiment uses the Agilent HP1100 system, the Agilent ODS C18 (150 mm × 4.6 × 5) column, mobile phrase selects acetonitrile -0. 017 mol/L oxalic acid (3 + 2) ; The examination wave length is 372 nm, enters the type quantity: 50 μL, Column warm: Room temperature. The plama is extracted by oxalic acid, then purify by C18. Sample pretreatment of this method is simply, the correlation coefficient can reache above 0. 999 89. The examination limits is 0.05μg/g, average recovery above 75% , coefficient of variation is below 6.6%. Sample pretreatment of this method is easily, the result is reliable, and with high sensitivity.
