Figure 1.7 Reversing the Sample Platform
Platform Release
The platform release is located on the left edge of the Sample Compartment, above the sample
platform in its lowered position (
Figure 1.4 , D ).
To lower the platform from its locked analysis position, push the top of the release towards the rear
of the compartment.
It is not necessary to use the platform release when raising the platform to the analysis run position.
External Electrode
The external electrode is located in the upper left corner of the Sample Compartment, just behind
or to the side of the aperture tube (
Figure 1.4 , E ).
The external electrode creates an electrical current that passes through the aperture orifice. As
particles suspended in the electrolyte solution flow through the orifice during an analysis run, the
Analyzer determines particle size by measuring the electrical pulse generated by each particle.
Stirrer
The stirrer is located at the top of the Sample Compartment, to the right of the aperture tube and
electrode (
Figure 1.4 , F ).
