When we calculate Impurity against impurity std.solution
and when we calculate impurity against diluted standard with
applying RRF?

Answer Posted / sp goswami

We need calc of imp RRF against impurity std when our
impurity responses are improper with st. phase of that
column and also if imp. is available in sufficient quantity
for diluted std we can cal for quantified results and if
impurity is less in amount and response is also less ,so to
get a perfect calculated % impurity we quantify it with
help of diluted std.

If change in specification which parameter require to do for validation? if change in chromtographic condition then which parameter? if api change then which parameter? if change composition then which parameter? if old method not work out then whicj parameter? if additional one impurity added then which parameter of validation require to do on above each conditions? elaborate separately
