WebJul 17, 2012 · If it is defined as the RRF of the impurity (the most common situation), it is used as a divisor. In that case, the RRF is ratio of responses: Impurity/Parent. Let's suppose your impurity has an RRF of 0.5. That means that for equal amounts, the impurity peak will be half as big as the parent peak. You divide by the RRF to correct for that.
