15.4.5.1 Decreased flow cell performance
Warning:
Use proper eye and skin protection when working with solvents.
Several actions can be taken to address decreased flow cell performance. Avoid unnecessary
polishing; take the next step only if the previous was not successful.
Steps to address decreased flow cell performance:
1. Electrochemical cleaning of glassy carbon WE: In the pulse mode, let the potential jump
b1 and -1 V for 10 minutes. Settings: t1 = 1000 ms, t2 = 1000 ms, t3 = 0 ms, E1 =
+1V, and E2 = -1V.
2. Wiping the electrode surface with a tissue wetted with ethanol or acetone.
3. Polishing the electrode surface.
15.4.5.2 Polishing
Notice:
Ensure that the SenCell is disassembled when setting it in position 0;
otherwise, it may damage the WE electrode surface.
Disassemble the SenCell. Set the WE block in position 0 (polishing position) using the
adjustment key ( 700013143) and turning it counterclockwise.
