The contents of the fatty acids were determined by using the normalization method 用峰面积归一化法得出各类脂肪酸的相对百分含量。
For the test of dissolution or release , the range should be 20 % of the limit 若含量测定与杂质检查同时测定,用百分归一化法,则线性范围应为杂质规定限度的- 20 %至含量限度的20 % 。
The relative weight correction factor of isooctyl was 1 . 036 , and its relative error was less than 2 . 0 % 同时,通过与化学法对照结果显示,合成液用内标法测定较好,而精产品用带校正因子的归一化法测定较好。
This method can only be applied to roughly test impurity content of test samples due to relatively big deviation produced by peak area normalization method 由于峰面积归一化法测定误差大,因此,本法通常只能用于粗略考察供试品中的杂质含量。
If the content determination and impurities test are to be done with normalization method simultaneously , the linear range should be - 20 % of the provided limit of impurity to + 20 % of the provided limit of content 若含量测定与杂质检查同时测定,用百分归一化法,则线性范围应为杂质规定限度的- 20 %至含量限度的20 % 。
34 chemical constituents of the essential oil from cortex cercis chinensis were separated and identified by gc - ms . the relative contents of them were determined by area nomaliation 摘要采用水蒸气蒸馏法从紫荆皮中提取挥发油,用气相色谱质谱联用技术对其挥发油成分进行分析,共鉴定了34个成分,并用面积归一化法确定各成分的相对百分含量。
