Applying Additional Capillary Cleaning Techniques (for S Series only)
In cases where polymers were sampled, the most likely cause of contamination is trace
polymer dried to the capillary. In this case, the polymer will probably require long term
soaking in the appropriate solvent to facilitate removal of the contaminant.
Using the solvent with the cleaning syringes after soaking (assuming compatibility),
should dislodge the residual contamination. Follow this with a DI flush, and, if
necessary, additional cleaning with a glassware cleaner.
Sometimes the source of contamination is aggressively attached to the surface of the
capillary. When these rare events occur, using cleaning syringes will not be sufficiently
effective to return the DC Light value to acceptable limits. Under these situations, using
a product called Super Floss
®
manufactured by Oral-B
®
, can sometimes dislodge the
contamination.
CAUTION
Do NOT use floss on the LiQuilaz II E20P particle counter. Floss will damage the capillary
on this unit.
>> To clean the liquid capillary using floss:
Follow these steps ONLY after an unsuccessful series of attempts to clean the capillary
with the syringes.
1. Isolate the particle counter from all fluid sources by disconnecting any tubing from
the inlet and outlet fittings.
