2998 gives baseline ripple at lower UV wavelengths - WKB191137
Article number: 191137
SYMPTOMS
- Baseline ripple at low UV wavelengths
- At UV wavelengths higher than 215 nm, the baseline ripple disappears
- Without mobile phase flowing by the flow cell, the baseline ripple disappears
ENVIRONMENT
- 2998
CAUSE
An incorrect stroke volume is configured in the instrument method.
FIX or WORKAROUND
Set the stroke volume to an appropriate value, as shown in the chart below.
