when you process the method validation of impurity,you can take the result of the linearity as the RRF.just the average value of the limit concentratin and the lower and the higer level,like80%,100%,120%.
when you cal the limit of the impurity,you only need the A1,A2 and the C2,then
C1=(1/RRF1-2)*A1/A2*C2作者: 小糖块 时间: 2011-11-15 14:59
