    Why is the baseline unstable with a large amount of drift and noise in SCIEX ExionLC Security Sensors?
    • K
      Katherine MossSep 10, 2025
      If your SCIEX Security Sensors baseline is unstable with a large amount of drift and noise, it could be due to bubbles trapped in the cell. To check, see if the baseline changes when you block the tip of the cell outlet tubing. If bubbles are flowing through the cell, perform corrective action to remove them.

    How to fix low lamp light intensity in SCIEX Security Sensors?
    • R
      Raymond WilliamsSep 12, 2025
      If the lamp light intensity is low in your SCIEX Security Sensors, it could be due to a dirty cell or the mobile phase absorbing strongly. Try cleaning the flow cell. Also, inspect the mobile phase solvent and flow lines to remove any impurities.
