Only a few <strong>of</strong> the shape distributions measured by the instrument are shown above. It is possible<br />

to display many other shape factors.<br />

The Morphologi G2 also stores all the particle images captured <strong>and</strong> used for the analyses. These<br />

images can be viewed using several sorting routines. A selection <strong>of</strong> these images appears below.
