Area counts differ between an Alliance 2695 HPLC with 2996 detector and the same with 2998 detector - WKB7884
Article number: 7884
SYMPTOMS
- Area counts are different on an Alliance 2695 HPLC with 2996 detector and an Alliance 2695 HPLC with 2998 detector when using the same column, mobile phase, and sample
- Peak shape is comparable
- RT is the same
- Values are reproducible
ENVIRONMENT
- 2996 Photodiode Array (PDA) Detector
- 2998 Photodiode Array (PDA) Detector
- Alliance 2695 HPLC System
CAUSE
The 2998 has an Autopurification Flow Cell [205000402] installed versus the Analytical Flow Cell Kit [205000399].
FIX or WORKAROUND
- Install the Analytical Flow Cell Kit [205000399].
- Rerun the sample.
