QUESTION:

What does Impurity RRF do?

Great question. Let’s find out.

In 2014, the Impurity RRF (Relative Response Factor) field was added to the Components table of the Processing Method. This field works in conjunction with the Impurity tab. It is used to adjust peak area when calculating % Adjusted Area, % Area against Main Component, and % w/w if w Value is Area. It will also adjust peak height when calculating % w/w if w Value is Height.

In this example, we selected % Area against Main Component as the Impurity Response on the Impurity tab of the Processing Method.

The initial result displays the Area and Impurity Response for Impurity B.

We then changed the Impurity RRF from 1 to 2 for Impurity B.

Empower multiplies the Area of the peak times two and uses that value to calculate the Impurity Response which is now double the original value.

It’s that easy!
