Split ratio:- It is the ratio of sample amount inject into
the column to that waste out from glass insert.
In capillary columns the size of bore is about 5 microns.It
faced xtra load whent inject high conc. sample.for reduce
the xtra load on column there is a need of split ratio.
Normaly its value:- 10:1
split ratio is required when Conc.of sample >or=0.1 %
split ratio is not required when Conc.of sample < 0.01 %

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.
