10.4 Interface maintenance
10.4.1 Cleaning the sampler cone
CAUTION
Plasma is extremely hot. Risk of burns!
Wait for approx. 5 min after extinguishing the plasma before servicing the interface
cones!
NOTICE
The tips of the interface cones are fabricated from nickel, so the orifices are fragile.
Take extreme care when handling the cones as microscopic defects in the cone tips will
have adverse effects on analytical performance.
NOTICE
After cleaning, any vacuum component (cones, O
-rings) should not be touched with
bare hands to minimize contamination of the system. Always wear clean gloves when
working inside the plasma interface.
Never use any grease or lubricants on the O
-rings.
Do n
ot use compressed air to dry the cones as it often contains oil vapor and the oil
will contaminate the cone surface.
The interface cones must be kept clean and free of deposits to ensure optimum
performance. How often you clean the cones depends on which samples you analyze.
Solutions with a high content of dissolved solids will cause deposits to form more
rapidly than solutions with low dissolved solids, so the cones will require cleaning
more often.
The sampler cone is held in place with a threaded retaining ring. A tool is provided to
loosen the ring so the cone can be removed.

The sampler cone tool has a spring-locking mechanism so the pins will clip into place
on the retaining ring when enough twisting force is applied in either direction.
