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.
