Why is my SCIEX ExionLC Security Sensors power not turning on?
- T
  Tina HuangAug 19, 2025
  If the power isn't turning on for your SCIEX Security Sensors, even after switching it on, there might be a few reasons. First, check if the power cable is properly connected. If the cable seems fine, it's possible the internal wires are damaged, in which case, replace it with the same type of cable. Also, ensure the power supply meets the module's specifications. If none of these steps work, the fuse might be blown, and you should contact an FSE to replace it.

What to do if SCIEX ExionLC baseline drifts?
- F
  Francisco ClarkAug 21, 2025
  If you're experiencing baseline drift with your SCIEX Security Sensors, it could be due to a few reasons. A common cause is liquid leaking from the cell inlet or outlet tubing joints, or from the cell itself. If you notice any leaks, wipe them up, dry the area, and perform maintenance to stop the leak. If the leak is coming from the flow cell window, soak up the liquid and tighten the cell window fixing screw. Another potential cause is looseness or a gap where the lamp and flow cell are installed. If you find any looseness or gaps, reinstall the components properly.

How to fix excessive noise in SCIEX ExionLC?
- A
  Ashley HarrisonAug 25, 2025
  If you notice excessive noise in your SCIEX Security Sensors, it could be due to a couple of factors. One possibility is insufficient lamp light intensity, so perform the lamp light intensity test. If the intensity is low, follow the corrective action for 'Lamp light intensity is low' or contact an FSE. Another cause might be a strong draft, like from an air conditioner, being drawn into the module. To resolve this, use a barrier to block the draft or move the module to a different location.

What to do if the error indicator illuminates on SCIEX Security Sensors?
- M
  Matthew MorrisonAug 27, 2025
  If you're seeing an error indicator light up on your SCIEX Security Sensors, it usually means there's been a transmission error or a liquid leak. Check the error code number and message, then follow the recommended steps for that specific error.

Why is there a large amount of drift in SCIEX ExionLC Security Sensors?
- V
  Virginia BarrettAug 28, 2025
  If you observe a large amount of drift in your SCIEX Security Sensors, it might be because the mobile phase and column are unstable. Try stopping the solvent delivery to see if the drift decreases. If it does, the mobile phase might have impurities or the column might not be fully equilibrated. Inspect the mobile phase, column, and analysis parameters.

How to prevent meandering baseline in SCIEX ExionLC Security Sensors?
- C
  cortezsharonAug 30, 2025
  If you're seeing a meandering baseline in your SCIEX Security Sensors, it's likely due to a strong draft affecting the detector. Try using a barrier to block the module's direct exposure to drafts. You can also install the module in a location with minimal temperature fluctuations and attach the provided insulation tube to the inlet plumbing.

What causes cyclical spike-like noise in SCIEX Security Sensors?
- M
  Mrs. Michelle MooneySep 1, 2025
  If you're experiencing a cyclical spike-like noise in your SCIEX Security Sensors, it could be due to the pump generating a large pulse or bubbles in the cell. To troubleshoot, first determine if the noise disappears when the LC pump is stopped. Also, verify the state of the LC pump for pulsation and eliminate any pulsation from the pump unit. Additionally, check if the baseline changes significantly when solvent delivery is manually stopped. If bubbles are present, take corrective action for bubbles.

Why does sawtooth-like noise occur in SCIEX Security Sensors?
- B
  Briana GoldenSep 3, 2025
  If you're seeing sawtooth-like noise (a repeating pattern of the baseline drifting upward, then suddenly changing downward) in your SCIEX Security Sensors, it's likely caused by small bubbles being temporarily trapped in the cell and then flowing out. To address this, put the tip of the detector drain tube in liquid to see if bubbles are exiting. If bubbles are flowing through the cell, perform corrective action for bubbles.

What causes random spike-like noise in SCIEX ExionLC?
- N
  natashagalvanSep 5, 2025
  If you're experiencing random spike-like noise in your SCIEX Security Sensors, it's often caused by bubbles flowing through the cell. To check, put the tip of the detector drain tube in liquid and see if bubbles are exiting the tube. If bubbles are present, take corrective action to eliminate them.

What to do if liquid is leaking from the cell of SCIEX ExionLC Security Sensors?
- R
  Ronald BassSep 7, 2025
  If liquid is leaking from the cell in your SCIEX Security Sensors, check the cell inlet and outlet tubing joints, as well as the cell itself, for leaks. If you find any, wipe up the liquid, dry the area, and perform maintenance to stop the leak. If the leak is coming from the flow cell window, soak up the liquid and tighten the cell window fixing screw.
