EP9.4中的2.5.12水分测定法适用性试验

分析员

EP9.4中的2.5.12水分测定法中试液/溶液适用性这个实验怎么做？可能英语水平的问题，研究好久没有搞明白X轴和Y轴到底是什么数值来做标准曲线的。求大神们赐教。原文是这样的：

The water content of the substance to be examined is determined using the reagent/solvent system chosen. Thereafter, in the same titration vessel, sequential known amounts of water, corresponding to about 50-100 per cent of the amount found in the substance to be examined, are added in an appropriate form (at least 5 additions) and the water content is determined after each addition.

Calculate the regression line. The x-axis represents the cumulative water added whereas the y-axis represents the sum of the initial water content determined for the substance (M) and the cumulative water determined after each addition. Calculate the slope (b), the intercept with the y-axis (a) and the intercept of the extrapolated calibration line with the x-axis (d).

谢谢！

X轴是标准水的累积加入量
Y轴是测得的样品中水分加上测定的标准水的量

有谁知道具体怎么做水分的适用性吗？是先测一次样品的水分，然后依次分别加入5次标准水吗？这样分开测有什么意义和联系？

请问，你们是怎么操作的
