At standard atmospheric pressure the contact
between the sample and the silver block is enough
to establish good thermal contact as the air mole-
cules in any minute scratches will conduct the
heat, but when pulling a vacuum these are drawn
out of the stage. Objective immersion oil
(supplied) has the same refractive index as quartz
and ensures an almost perfect thermal seal be-
tween block and crucible.
Using either the dropper or micropipette place a
tiny drop of oil on the silver block. Be careful not
to place the oil over the aperture hole of the silver
block.
Use the supplied Vacuum Tweezers or a pair of
tweezers place a clean W16Q, (16 x 0.3mm)
Quartz Sample Window directly on top of the oil
inside the G16.3 Sampler Holder.
Adjust the XY manipulators by a few turns in
both directions to spread out the oil underneath
the Quartz Sample Window evenly.
Using a pair of tweezers place a Shim Spacer (1)
in the middle of the Sample Holder.
