NOTE
All descriptions in this procedure are based on the default orientation of the cell (as it is manufactured). The heat exchanger/capillary and the cell body can be fixed mirror symmetrically to have both capillaries routed to the bottom or to the top (depending on the routing of the capillaries to the column).
-
Use a 4 mm hex key to unscrew the window assembly (1) and remove the gasket (2) from the cell body.
If you want to replace the gasket only, reinsert the window assembly into the cell body.
Use a tooth pick to remove the quartz window from the window assembly.
NOTE
If the washers fall out of the window assembly, they must be inserted in the correct order with the PTFE ring to prevent any leaks from the flow cell window.
