7.21 Replacing the LockSpray II reference probe

The LockSpray II reference probe differs from the original LockSpray reference probe in that it
comes as one complete unit, pre-built to length. The capillary end connects to the reference
sprayer assembly within the LockSpray II source housing.
Important:
There is no LockSpray II retrofit option for the LockSpray source, but the front-end
housings are interchangeable on the instrument.
Replace the LockSpray II reference probe if it becomes blocked and you cannot clear it, or if it
becomes contaminated or damaged.
Notice:
To prevent pressure from ejecting the capillary from the reference-
sprayer assembly, firmly tighten the finger-tight PEEK nut and ferrule.
