Capillary flow cell
To access and remove the flow cell assembly:
CAUTION! The inlet and outlet tubing on the
capillary flow cell are fragile. Be careful when
opening and closing the front door of the detector
and removing the cell. If broken, this tubing cannot
be replaced.
1 Open the detector's front door.
2 Using a 5/32" Allen wrench, remove the two
screws on the front of the detector block and
move the block to the side.
3 Using a Phillips screwdriver, remove the flow
cell assembly screw. Then pull the flow cell
assembly towards you to remove it.
To replace the flow cell assembly, replace the
detector block, and close the detector door:
1 Insert the flow cell assembly into the detector
and tighten the flow cell assembly screws. The
assembly can be oriented so that both ends of
the tubing exit either the top or the bottom of
the flow cell.
2 Replace the detector block making sure that the
tubing passes through the slot on either the top
or the bottom of the detector block. Tighten its
two screws.
3 Route the tubing through the cutout, located at
the lower left of the detector's front door.
4 Close the detector's front door.
