FTIR is the process by which a sample is placed into a KBr
pellet or mineral oil mull and subjected to infrared
radation (waves of light from the IR part of the light
spectrum). The IR light is then partially
absorbed/transmitted by the bonding of the molecules within
the sample by their streching & bending. This absorption
is then represented graphically with a spectrum from 450 -
4000nm. This is a fingerprint of the substance (best
results are obtained with pure samples).

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.
