Fusion sequence
When the user instructs the K1 Prime to launch the actual fusion, all heating steps
are automatically started in sequence. Temperature is constantly monitored and
displayed.
Once the flux is molten (after a programmable time), a back-and-forth rocking of
the crucible heater continuously mixes the flux with the sample.
The liquid flux starts dissolving the sample. When all sample is dissolved (after the
programmed time), the crucible heater tilts forward and the crucible pours its
contents into the mold.
If set so in the fusion program, it is possible for the now-full mold to be re-heated
by its heater, before the final cooling. (This operation is called
annealing
and is
needed in very special cases only.)
A blower located underneath cools the mold; when the mold is completely cooled,
the user picks up a perfectly homogenous glass bead, ready for analysis by XRF.
For solution preparation, the hot melt is poured into an unbreakable beaker
(instead of a mold), which contains a dilute acid that is automatically stirred by a
magnetic system (optional).
Some fusion types, such as peroxide and pyrosulfate, do not even require
pouring. The K1 Prime is also designed for such fusions, where the whole crucible
is dipped into an acid, after the fusion, to prepare a solution by leaching.
