欧洲药典中在有关物质检查项下,规定各个杂质限度及总限度后还会列出disregard limit 不知道disregard limit 指的是什么?哪位高手能给降解一下,谢谢! 例如: Limits:--impurity A:not more than 1.5 times the area of the correspongding peak in the chromatogram obtained with the reference solution(1.5 percent) ---any other impurities:...... ---sum of impurities other than A:.... ---disregard limit: 0.05 times the area of the peak due to rifampin in the chromatogram obtained with the reference solution (0.05 per cent)
