Maintaining the flow cell 4-15
Replacing the flow cell
The detector is shipped with a standard analytical flow cell installed. Replace
the flow cell when
• the flow cell becomes damaged.
• you want to use one of the optional flow cells (see the table on page B-5).
To prepare for replacing the flow cell:
1. Unpack and inspect the new flow cell.
2. Power-off the detector and disconnect the power cord.
3. Remove the front left panel cover.
4. Disconnect the detector inlet/outlet tubing from the main column
connection and cap.
To replace the flow cell:
1. Using a 1/4-inch flat-blade screwdriver, loosen the three captive screws
on the flow cell assembly front plate (see the figure on page 4-8).
2. Gently pull the assembly toward you.
3. Insert the new flow cell assembly into the detector.
4. Tighten the captive screws.
5. Reconnect the inlet/outlet tubing to your LC system.
6. Reconnect the power cord, and then power-on the detector.
Caution: To prevent contamination, use powder-free finger cots or
gloves when disassembling, inspecting, cleaning, or replacing parts
within the Waters TaperSlit Flow Cell or when removing or
replacing the flow cell within its assembly.
