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。
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。
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。
