GPC calibration "Invalid Curve: Do Not Use For Quantitation" in Empower - WKB196122
Article number: 196122
SYMPTOMS
- GPC calibration "Invalid Curve: Do Not Use For Quantitation"
ENVIRONMENT
- Empower
CAUSE
The curve changes slope in the calibrated range.
If the curve flattens at either end of the calibration range, determine if the standards are within the operating range of the column set.
FIX or WORKAROUND
Change columns to match the calibrated range, or change standards to match the range of the columns. This should be based on the MW range of the samples to be analyzed.
