The sample preparation of samples containing bovine serum albumin (BSA), as used in transdermal Franz diffusion cell (FDC) solutions, was evaluated using an analytical quality-by-design (QbD) approach. Traditional precipitation of BSA by adding an equal volume of organic solvent, often successfully used with conventional HPLC-PDA, was found insufficiently robust when novel fused-core HPLC and/or UPLC-MS methods were used. In this study, three factors (acetonitrile (%), formic acid (%) and boiling time (min)) were included in the experimental design to determine an optimal and more suitable sample treatment of BSA-containing FDC solutions. Using a QbD and Derringer desirability () approach, combining BSA loss, dilution factor and variability, we constructed an optimal working space with the edge of failure defined as <0.9. The design space is modelled and is confirmed to have an ACN range of 83±3% and FA content of 1±0.25%.
采用分析质量源于设计(QbD)方法,对用于经皮弗兰兹扩散池(FDC)溶液中含牛血清白蛋白(BSA)样品的制备进行了评估。通过添加等体积有机溶剂对BSA进行传统沉淀,这种方法常用于常规高效液相色谱 - 光电二极管阵列检测(HPLC - PDA),但在使用新型融合核高效液相色谱和/或超高效液相色谱 - 质谱(UPLC - MS)方法时,发现其稳健性不足。在本研究中,实验设计纳入了三个因素(乙腈(%)、甲酸(%)和煮沸时间(分钟)),以确定含BSA的FDC溶液的最佳且更合适的样品处理方法。使用QbD和德林格合意性()方法,结合BSA损失、稀释因子和变异性,构建了一个最佳工作空间,将失败边缘定义为<0.9。对设计空间进行建模,证实乙腈范围为83±3%且甲酸含量为1±0.25%。
