PARTICLE COUNTING A NEW SAMPLE 8
Select a Container for the Sample - A clean, high quality glass container such
as a 120 mL beaker (Grade A quality) or extruded glass bottle of no less than
2 ¼” in diameter should be used. The quality can be checked by holding it up to
the light. If it has the smooth appearance of a sheet of window glass, it is
suitable. If it has many striations parallel to its base, it should be rejected.
(Spectrex has high quality beaker sets and glass bottles that may be purchased.)
Simple Five Step Counting Procedure (*w/o computer attachment):
*Refer to the SuperCount™ Software Manual supplement for procedure
w/ computer attachment.
1. Turn on the Particle Counter. A laser beam will appear from the
projection box toward the front of the instrument. Use the light-tight
cover to protect from fluorescent light.
2. View the red circle, approximately 3 mm in diameter, projected in the
center of the black target in the middle of the collector lens.
3. Ensure the threshold
setting is at the 1µm level. This is normally
either 10 or 11 on the threshold knob dial.
4. Resuspend the sample by swirling/stirring to ensure a homogenous
suspension. Place the sample firmly onto “V” block. The container
should be extremely clean, with no smudges, fingerprints, or dust on
the glass wall.
5. Press the Count
button. The readout in the display window, when the
counting has stopped, indicates the number of particles per cubic
centimeter (milliliter) above 1 µm.
