Binary Mixtures—

specified ratio of 50:50 —Thirty percent of 50 is 15% absolute, but this exceeds the maximum permitted
change of ±10% absolute in either component. Therefore, the mobile phase ratio may be adjusted only
within the range of 40:60 to 60:40.


specified ratio of 2:98 —Thirty percent of 2 is 0.6% absolute. Therefore the maximum allowed adjustment
is within the range of 1.4:98.6 to 2.6:97.4.

分解一下,二相流动相的调整比三相的简单多了:

当流动相比例是50:50时,

1. Thirty percent of 50 is 15% absolute, but this exceeds the maximum permitted change of
±10% absolute in either component.


2. Therefore, the mobile phase ratio may be adjusted only within the range of 40:60 to 60:40.


当流动相比例是2:98时,

3. Thirty percent of 2 is 0.6% absolute.


4. Therefore the maximum allowed adjustment is within the range of 1.4:98.6 to 2.6:97.4.

二元混合物——
规定比例为50:50时——50的百分之三十为15%,但这超过了各组分最大允许调整值±10%。因此流动相比例仅可在40:60 -60:40的范围内调整。
规定比例为2:98时——2的百分之三十为0.6%。因此流动性比例的最大允许调整范围为1.4:98.6 -2.6:97.43。
