Based on the final concentration of the samples/standards
used for the validation of the method, homogeneity and
stability, the linearity plot (Concentration Vs Area) will
be plotted which covers the final concentration with ± 50%
range. so that analyzed concentration of the
samples/standards will fall within these range which is
acceptable.

In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.
