The process is based on the simultaneous disintegration
and mixing of sample materials with volumetric reduction, using
two high-speed blades in a beaker.
The materials used are also suitable for the purposes of trace
element analysis. In this case you should consult the matrix
of materials in Section 9, Appendix.
Starting point: Sample material in the beaker, the beaker in
position, the safety door closed.
• Beaker plus contents move up to the cutter.
• As soon as the whole cutter is inside the beaker, it begins to
rotate.
• When the cutter reaches maximum speed, the beaker plus
contents move up to the cutter.
• The membrane pressure automatically accomodates the
sample volume.
• The sample is disintegrated and mixed simultaneously.
• The beaker plus contents moves down far enough for the
cutter to coast to a stop while inside the beaker.
• The beaker plus contents moves down away from the cutter.
