Cleaning the folded capillary cell
This cell is intended to be used once then discarded. We recommend that, before a
cell is used for the first time, it is flushed through with ethanol or methanol to facil-
itate wetting. A syringe or a wash bottle can be used. Use only sufficient fluid to
wet the surface of the cell and electrodes.
The cell should then be flushed through with water as described below.
To clean the cell:
Fill one syringe with de-ionised water or the dispersant.
Place the full syringe in one of the sample ports on the cell and the empty
syringe in the other.
Flush the contents of the full syringe through the capillary cell into the empty
syringe.
Repeat the flushing process five more times, flushing the liquid backwards and
forwards between the syringes. The cell is then ready for use.
Never
attempt to clean the outside of the folded capillary cell. It causes small
surface scratches that give inaccurate results.
