UNIFI does not find peaks - WKB68317

SYMPTOMS

• UNIFI does not find peaks

ENVIRONMENT

• UNIFI

CAUSE

Retention Time Compound-specific settings are too tight.

FIX or WORKAROUND

1. Note that there are two places in UNIFI to set Retention time tolerance windows for a compound of interest. The Retention Time Tolerance window for a compound is set as a global parameter in the processing method. And the tolerance window is set for each compound in the compound-specific list.
2. If a peak is not being found, ensure that the tolerance window is wide enough in both places to not exclude the peak of interest.
