Sample
Preparation
The method used to prepare and load your
sample varies according to the sample type.
There are two methods available for the film/
fiber accessory: aluminum balls or stainless
steel clamps.
Using the
Aluminum Balls
The aluminum balls are generally used with
fiber samples as follows:
1. Measure and cut the fiber sample slightly
longer than desired length, typically 12 to 25
mm (0.5 to 1.0 inch).
2. Place two cleaved aluminum balls 12 to 25
mm (0.5 to 1.0 inch) apart.
3. Lay the fiber across the balls and press the
fiber into the cleavage of each ball (see
Figure 4.3).
