LiQuilaz II E and S Operations Manual
Chapter 3 Maintenance
Required materials:
• Capillary cleaning kit
• A standard laboratory glassware cleaning solution
Cleaning Solution
When selecting an appropriate cleaning solution, consider the types of contamination
that will have deposited onto the capillary from the most recent fluid sampled.
For instance, if DI water was sampled last, bacteria, or particles are the most likely
sources of contamination.
If solvents were sampled last, optical hazing due to chemical impurities is most likely.
Both of these situations can be easily remedied using high-quality laboratory
glassware cleaner such Micro-90® or Radiacwash™. A 5% solution of glassware cleaner
in ultra-pure DI water should be used.
CAUTION
Do NOT remove the 4-40 socket head screws from the fittings. Doing so will compromise the
capillary seal and result in fluid leaking onto circuit boards and extensive damage.
Only remove 3mm zero dead volume fittings from the inlet/outlet connections.
WARNING
Before removing the LiQuilaz II Liquid Particle Counter from a CLS-700 sampler, make sure the
sample inlet and outlet tubes are first connected together, or directed into an appropriate drain.
Failure to do so could result in severe personal injury, as water from the sampler will be forced out
of the open tubing under pressure.
