评定固相萃取-HPLC法测定人血清中10-羟基卡马西平浓度的不确定度
Uncertainty evaluation for the determination of 10-hydroxycarbazepine in human serum by solid phase extraction-HPLC
摘要
Abstract
Objective To evaluate uncertainty for the determination of oxcarbazepine active metabolite (10-hydroxycarbazepine) in human se-rum by solid phase extraction -HPLC.Methods The uncertainty caused in the whole process of determination was analyzed.Sources of uncertainty were established and simplified, then each component of un-certainty, combined uncertainty and expanded uncertainty were calculat-ed by using the method validation data in accordance with the evaluation procedure.Results The expanded uncertainty for low, medium and high concentrations (3.18, 12.73, 50.91 μg· mL-1 ) of 10-hydroxy-carbazepine was 0.24, 0.44 and 1.66 μg· mL-1 , respectively ( k =2, P=95%).Conclusion The uncertainty of this method was mainly caused by calibration curve fitting ( especially low level of sample ) , serum drug extraction, serum sample preparation, HPLC error and measuring repeatability.关键词
