2998 PDA detector - excessive baseline noise - WKB13746

SYMPTOMS

• Excessive, irregular baseline noise

ENVIRONMENT

• 2998 PDA detector

CAUSE

Poor flow cell condition

FIX or WORKAROUND

1. Rebuild the flow cell using the appropriate rebuild kit. 
2. Replace flow cell if rebuilding the flow cell does not resolve the baseline issue.
3. Run Noise / Drift test to confirm functionality 

ADDITIONAL INFORMATION

You can apply the resolution described here to a failure of the UV detector SQT noise and drift test.
