2 Scanning
Using the Sample Crusher
CAUTION
DO NOT scan pressure-sensitive materials
with the sample crusher (see
page 9 ).
Whenever possible, use the sample crusher to scan
powders, because it is difficult to manually apply
enough pressure to get a good scan. The sample crusher
holds a powdered sample in firm and close contact with
the sampling tip during the scan.
1
Place the sample crusher on a level surface.
2
Clean the sampling platform with an alcohol wipe.
3
Place a small amount of sample material in the
center of the sample platform.
Use only enough
material to completely cover the center of the
platform.
4
Perform steps 1 through 5 of the scanning procedure
(see
page 13 ). Do not put the instrument into the
sample crusher until the instrument has finished
the background scan.
5
Press the instrument into the sample crusher (see the
figure at the left) until the side latches snap into
place. If you have trouble inserting the instrument,
you may need to clean the sample crusher (see
page 42 ).
TIP
To minimize the risk of dislodging the sample
during insertion, hold the instrument at a
slight angle on the front-to-back axis and
insert the nose into the crusher, then
straighten the instrument and push it down
to complete the insertion.
6
Initiate the scan (see step 6 on page 14 ).
7
When finished, press the latches to release them, and
remove the instrument.
NOTE
If the scan progresses slowly, remove the
instrument and reinsert it into the sample
crusher. If scan time does not improve, stop the
scan, remove the instrument, and make sure
that the sample is centered on the sample
platform.
