【每日一句(段)有奖翻译】<七>色谱条件的调整(流动相3)

如果流动相由三种成分组成，当系统适用性达不到要求时你是如何调整流动相的呢？怎样调整才是在药典允许的范围内呢？下面是一个典型的例子，解释得比较复杂，还是分开一句一句的翻译吧:

1. For the second component, 30% of 35 is 10.5% absolute, which exceeds the maximum permitted
change of ±10% absolute in any component.

2. Therefore the second component may be adjusted only within the range of 25% to 45% absolute.
For the third component, 30% of 5 is 1.5% absolute.

3. In all cases, a sufficient quantity of the first component is used to give a total of 100%.

4. Therefore, mixture ranges of 50:45:5 to 70:25:5 or 58.5:35:6.5 to 61.5:35:3.5 would meet the
requirement.
