Aluminum Sample Pelletcups
Transform powdered samples into firm durable solid
briquettes protected on all sides excepting for the surface to
Minimizes potential hazards of breakage, easy to handle and
introduce into briquetting dies. Simply fill a PelletCup with
the powdered sample substance, place into die and briquette
in usual manner.
Select from the "ORIGINAL" Tapered-Walled PelletCups in
Aluminum and Plastic or Straight-Walled
Tapered-Walled, Aluminum PelletCups are the "ORIGINAL"
PelletCups and most popular and versatile for briquetting
a wide range of powdered samples under diversified
pelletizing conditions. Taper tends to reduce cracking
and fissure development. Very close outside diameter
tolerance minimizes sample particles spilling over and
becoming entrapped in between the inside walls of the die
and PelletCup. Filled PelletCups gently float down into the
die cavity on a cushion of entrapped air further reducing
likelihood of spillage.
Tapered-Walled, Plastic PelletCups are similar to their
"ORIGINAL" aluminum counterparts excepting shallower
and accommodating less sample volume. Lubricious plastic
quality helps extend die life by resistant-free pellet ejection.
Straight-Walled, Aluminum PelletCups have perpendicular
walls with respect to the flat bottoms and smaller diameters.
Straight-Walled PelletCups are acceptable where spillage;
potential cracks and fissure development from stress and
strain are not important issues.

Grinding and Briquetting Additives
Most powdered sample substances are considered
multiphased or compositionally complex. They are
comprised of individual particles or crystal phases
frequently dissimilar in composition, density, hardness,
configuration, size and distribution. Each particle tends
to behave as a separate entity from its surrounding
constituents. Chemplex grinding and briquetting additives
are formulated to aid in the grinding and briquetting
process by reducing particles to a uniform size and
distribution forming a homogeneous sample blend for XRF
analysis. Under briquetting pressure, the powdered samples
are transformed into "plasticized" pellets with smooth
unblemished surfaces resistant to inadvertent chipping or
flaking apart. Samples may be saved for future referral.
In preparing powdered samples requiring a grinding or
briquetting additive, it is most advantageous to use the
least amount of additive to minimize the effects of dilution
unless the use of the additive is for dilution purposes. As
a starting point, use 1.0 to 2.5 wt% additive of the sample
weight, e.g. 0.1 to 0.25 g additive, to 10 g sample. Adjust the
amount of additive until the desired results are obtained.
Alternatively, the additive weight may be held constant and
the sample weight quantity varied for applications that
will be utilizing the convenience of pre-weighed tablets.
To maintain compatibility, standards should be similarly
