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.
