Subraction of a blank CF
Custom field required : Area_subr = Area-(BL(Area)) taken blank area from blank injection labelled BL then use this in Y-value for quantification (replace Area with Area_Subtr
Works fine in calibration curve but also subtracts blank area from sample - unknowns
If CF type standards only then does not work (assuming since Blank injection is an unknown)
Only want to subtract blank from standards for quantification purposes
Any ideas ?
