Shape Analysis / Image Analysis
Image analysis allows information about a particle's shape to be obtained. Shape anlysis is performed by taking pictures of the particles and then using a computer to determine various parameters about the particle such as cross-sectional area, perimeter, Feret diameters, equivalent spherical diameter and many more.

Particle Technology use the DIPA 2000 to perform dynamic image analysis. This means instead of capturing single images under a microscope and then processing them, the analyser has a flow system and a fast camera that takes many images per second and processes them instantaneously. This technique means that many thousands of particles can be processed so that you can be sure of accurate and representitive data.
Image analysis allows us to chracterise material that was previously very difficult or impossible such as fibres and needles. We can determine a fibre's width, length and even calculate curl index; all of these parameters can then be plotted so that trends and patterns can easily be identified. Another very popular use of image analysis is to determine the sphericity of particles, this is employed for high value particles such as polystyrene beads used in calibration or ion exchange where a perfectly regular shape is essential and must therefore be monitored.
