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.

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
