Cleaning
Exterior
Clean the external surfaces by applying one of the following solvents to a clean cloth and wiping.
NOTICE
Do not maintain contact between the solvent and the surface for more than 15 seconds.
The external surfaces of the housing may be cleaned with the following cleaning agents:
●
Isopropanol
●
Methanol
●
Ethanol
●
Sodium Hypochlorite (15% Bleach)
Conductivity Flow Cell
Follow these instructions if you need to clean the flow cell, unclog the flow cell, replace the inlet or outlet
tubing, or replace the flow cell.
NOTICE
Be extremely careful when working with the flow cell and its fittings. Flow cells are
considered expendable and are not covered by warranty if damaged or broken during any
maintenance procedure.
CLEAN THE INSIDE OF THE CONDUCTIVITY FLOW CELL
Increased noise and reduced sensitivity can be a result of a dirty flow cell.
It is often sufficient to clean the flow cell to restore optimal performance.
CAUTION
To prevent injury, observe good laboratory practices when handling solvents. Know the
physical and chemical properties. Refer to the Material Safety Data Sheets for the solvents
used.
To clean the inside of the flow cell:
1. Pump deionized water through the flow cell at 2–5 mL/min for 10 minutes.
2. Check monitor performance by running a sample through the system.
3. If the cleaning does not have the desired effect, repeat cleaning procedure, but substitute methanol for
deionized water.
