we calibrate HPLC once in 6 months while iam doing
calibration i came to know that calibration was failed.
then how can i justify that the samples analyzed on the
system during this 6 months was wright? how can i forward in
to the next step for those batches?
Answer Posted / k l reddy
Need not to analyze all previous batches but you should
analyze 6 previous batches(recent batches of before
calibration)on different system(which is qualified) and
compare the results with old results. Fallow the same
prociser until the resukts matched with old results.

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.
