5.3.1 Clean the conductivity flow cell
Maintenance interval
Clean the conductivity flow cell when the signal is unstable or when unexpected readings
are obtained.
Required material
The following materials are required:
•
Luer-to-SNAP connector (see Luer-SNAP 3.2 connectors, on page 25)
•
Waste container (for example, 250 mL flask or beaker)
•
Syringe, 25 mL
•
1 M NaOH
•
Distilled water
Procedure
Follow the steps below to clean the conductivity flow cell. The same procedure applies
to both pre- and post-column conductivity monitors.
WARNING

to health. When using hazardous chemicals, avoid spillage and
wear protective glasses and other suitable Personal Protective
Equipment (PPE).
ActionStep
