Can you only have a Curve Reference if you process samples sets including 'Amount'?
I have a related impurities test which tests % impurity by the following formula:
Area of impurity*RRF*100/Area of Active. I have a custom field for this which works well ie Area*RRF*100/CCalRef1[Area] but how do I take into account the RRF and does Empower automatically assign an unknown peak with an RRF of 1? I know you can select a curve reference and that gives you a space to enter RRF but for my custom field to work on all knowns and unknowns would I have to NAME all peaks in my sample then calibrate and quantitate to process the sample set?
If I use the default peak option, wont this only calculate unknowns is some kind of calibration and quantitation occurs? Currently results are written up on Excel..

The impurities tab is designed to eliminate this particular gap when processing impurities: when you need a default value for an unnamed peak (not in your component table). I believe you can set up a general/default RRF but I'm no expert
You might think of creating your own custom field for RRF rather than using the built in one. You could then set a default value for that field which will only be modified if the CConst value is entered. RRF=CConst5; Default value 1.2
There may be a way to use the Default peak for all unknowns in a region. The unknown peaks may pick up the RRF value but again, its been a long time.
I think there are may ways to skin this particular cat0

The following is rough and untested, but something like: EQ(Peak Type, "Found"). If it is a found peak, it will return a 1 which would be translated to "ImpFound (fc)" in your translation definition. If not a named component, it would return a 0, which you would translate to "ImpUnk (fc)" in the translation definition. You'd then report the result of the boolean field (not the called sub-field) for any final result.
Just as another catch...ensure you've properly configured the fields for Founds and Unknowns.
