7.6.1 Guidelines for Handling Flow Cells
NOTICE
Flow cells are highly sensitive to dirt and dust. Observe the following
notes when handling flow cells:
• When holding flow cells, do not touch the optical block of the flow
cell or the sensitive electronics on the flow cell rear side.
• The optical ports of the flow cell are sensitive to contamination and
scratches. Do not touch the optical ports of the flow cell or immerse
them.
• To avoid damage to the optical ports of the flow cell, be careful
when inserting the flow cell into the flow cell opening of the device.
• On the rear side of the flow cell, the contact pads for the
identification chip are located. Never touch the contact pads. Avoid
damage to the electronics of the ID chip.
• Particulate matter, dust and debris can lead to contamination and
clogging of the flow cell. If capillaries are removed from the flow cell
inlet and outlet, install protective plugs to close the ports and to
prevent particles from clogging the flow cell in the next application.
Always use the plugs that were installed when the flow cell was
shipped.
• Use the dedicated packaging when storing or transporting the flow
cell.
7.6.2 Cleaning the Flow Cell
When
When you suspect that eluent or sample components may have
deposited on the flow cell windows.
Parts required
• Flushing and injection kit for flow cells (optional)
• HPLC-grade water
• 0.1 M nitric acid
