INTRODUCTION 1
The Spectrex PC-2300, In-Situ Particle Counter, is a unique and easy-to-use
instrument designed to permit thorough inspection of liquids without consuming
the sample. It is ideal when critically clean liquids are needed. A laser beam
permits observation of small particles by near-forward light scatter. In addition, a
scanning and detection system is provided to automatically quantify the number
of small particles in one cc (milliliter) of the contained liquid.
Sealed calibration standards are provided so that quality control levels may be
established against which individual samples may be compared. An analog
output is provided for computer interfacing to give automatic particle sizing and
counting results.
A specially designed fixture, the “V” Block, automatically holds in correct
alignment any standard 150 mL beaker or calibration standard. The spring
automatically pushes the bottle up into the “V” position. It is easily removed (by
unscrewing two 6/32 screws) for small vial or flow-thru cell attachment.
The Model PC-2300 Particle Counter provides all of the facilities needed for rapid
inspection of bottled and flowing liquids. Small particulate matter is automatically
quantified by a scanning laser beam and the results presented on a digital
display. A minimum size selector is provided for this quantification measurement
and is normally set to 1µm.
The direct hookup to a computer with interface card, cable and software
(provided by Spectrex) give full, automatic sizing and counting of particles. The
PC-2300 is ruggedly constructed with all the optical members mounted on one
solid aluminum base plate. Thus, the instrument should never go out of
alignment.
