NOTICE

Flow cells are sensitive to damage and contamination.

Operating conditions

Observe the specified maximum pressure limit for the flow cell. See the specifications for flow cells in Flow Cell Specifications.

Interrupted operation

If the pump flow is interrupted, take appropriate measures to protect the flow cell:

  • Turn off the UV lamp or close the shutter to protect the flow cell from the light of the UV lamp. UV radiation from the lamp may damage the flow cell.

  • Never leave any substances in the flow cell without flow. Particularly avoid leaving any aggressive solvents in the flow cell for a longer time.

  • Without flow, air bubbles in the flow cell can accelerate the deposition of substances. Never leave air bubbles in the flow cell. If the pump flow is stopped for a longer time, fill the flow cell with a high purity solvent, for example isopropanol.

Troubleshooting flow cells

  • If a flow cell leaks, stop the pump flow, remove the flow cell from the detector as quickly as possible, and replace the flow cell.

  • For information about how to clean a flow cell, see Cleaning the Flow Cell.

Storage and shipment

  • Always keep unused flow cells in their original dust-free packaging.

  • When shipping the instrument, remove the flow cell and install the diagnostic cell to protect the flow cell opening. The flow cell must be shipped in its original packaging.
