Our GALAI (CIS-100) stream-scanning laser particle sizer uses laser-based measurements of "time of transition" to determine particle size and uses image analysis to determine particle shape. Image analysis uses high-resolution digital video camera, microscopic lenses and powerful software to capture and analyse particle images many times a second. Importantly, the technique provides some 60 particle-shape parameters (e.g., particle aspect ratio, sphericity, perimeter length, surface area). The GALAI quickly counts large numbers of particles, providing good statistics on size and shape populations.
