Why am I not getting values for USP noise, JP noise and EP noise? - WKB6683
Article number: 6683
SYMPTOMS
- USP signal to noise, JP signal to noise, and EP signal to noise are calculated
- There is no value for USP noise, JP noise or EP noise in the Peaks table
ENVIRONMENT
- Empower 3
- Regional Pharmacopoeia
CAUSE
You did not select the option "Use noise centered on peak region in blank injection" in the processing method's system suitability tab.
FIX or WORKAROUND
- Select "Use noise centered on peak region in blank injection" in the processing method's system suitability tab.
ADDITIONAL INFORMATION
If you do not select "Use noise centered on peak region in blank injection", the software still calculates the USP, JP, and EP signal to noise using Peak to Peak noise. The software does not calculate values for the Empower fields labeled USP noise, JP noise, or EP noise.
