Sensitivity test for indicators solution


(Sachin Sathe) #1

Dear sir,
I am using the redy made solution of indicators (eg. Merck Phenolphthalein indicator 1.0%) for titration and assay analysis.
my question is that, it is regulatory requirement to do the sensitivity test for the indicator solution or it is acceptable to use redy made indicator solution???

please suggest me.
