7. Carefully push the cleaning brush into the cell this distance and pull
out but maintain the 3/4-inch difference between in and out and do
not pull it out of the cell completely. The limitations prevent the
brush from exiting the flow cell inside the sensor, which may allow
the brush stem to scratch the sapphire cell wall, which will void the
instrument warranty.
8. Repeat the brush cleaning 8 to 10 times.
9. Remove the brush and reconnect the flare tubing to the Inlet and
Outlet Nozzles.
10. Make sure that all tubing connected to the RLPC are securely
connected.
WARNING:
Do NOT
allow any liquid that has
been used to flush the
sensor of contamination
to re-enter the sampling
system.
11. Turn on liquid flow through the RLPC for one minute to flush any
bubbles and residue out of the flow cell. This liquid should NOT be
allowed to re-enter the sampling system and should be safely
discarded.
12. Reconnect power to the RLPC and verify the service light is off to
determine if the flow cell was cleaned successfully.
