4. Put enough sample material into the pellet
press to yield a 0.25 to 1.00 mm thick disc
(~30 to 50 mg).
5. Place the pellet press piston into the cylinder
and add a suitable weight (50 g) on the top
of the piston.
6. Note the position of the piston in the cylin-
der; as the sample starts to melt, the piston
will settle.
7. Using tongs, remove the weight when the
piston sinks to its maximum depth.
8. Remove the mold assembly from the hot
plate using tongs, and allow it to cool to
room temperature.
9. Disassemble the mold and remove the
molded sample disc.
10. Measure the sample thickness, using cali-
pers, to 0.02 mm.
11. Place the sample between two parallel plates
in the alignment cage as shown in Figure
4.14 on page 4-37.
12. Load your sample according to the direc-
tions on page 4-41.
