Empower3 - Pass / Fail R^2 - Custom field

[artsjeroen]

Hi all,

I'm trying to create a boolean custom field in Empower for an R^2 >= x

I've tried:

GTE((R^2),0.998)

However, R^2 is a result, and for a result custom field I get "A peak/component field cannot be used without SUM, MIN, MAX or AVE when creating a Result type custom field.

All results refer to one calibration curve.
How can this be done?

Simple :
Create a CF type peak that refer to R^2
Use your new CF in your formula

For some reason the R2 is different per standard injection.
I've added a calibrate line at the end of the sample set, but this makes no difference.

try this as a guide , though not sure why R2 is different for each standard
Calibration type total maybe:

Hi
Modify the field type to PEAK! It will work.
