全血中氯霉素的固相萃取方法
[Abstract]:Objective to establish a solid phase extraction method for chloramphenicol in whole blood. Methods the standard chlorine toxin was added to the blank blood. The linear range, precision and recovery were determined by HLB,MCX solid phase column extraction. Results the recoveries were 69.1%, 6.21%, 70.1% and 4.34%, respectively. The standard working curve was 18.1094 X-0.4822, the correlation coefficient was 0.9999, the linear range was 1.0 ~ 20.0ugr / L, and the minimum detectable amount was 3ng. The standard added working curve was Y ~ (-2.1165) X 14.0459, the correlation coefficient was 0.9996, and the minimum detection limit was 0.5 渭 g/mL (S/N=10:1). Conclusion these two extraction columns can be used for solid phase extraction of chloramphenicol.
