To measure particle size distribution accurately, the Eyetech records on-centre and in-focus interactions only. This is achieved by filtering the shape of the Pulse Profile via sophisticated algorithms. When a particle is hit by the laser beam straight on, the slope of the Pulse Profile approaches an angle of 90 degrees, resulting in short pulse transitions. In off-centre or out-of-focus hits, the angle between the laser path and the particle boundary is significantly less then 90 degrees. Consequently, the rise and fall times of these interactions are longer and the derivative signals of the pulse transition are wider have smaller amplitude and can therefore be easily discarded. One benefit of the Laser Obscuration Time principle is that there is no assumption of particles sphericity. Furthermore, the particle size measurement is solely based on the length of the cord crossed by the laser, regardless the shape of the particle thus guaranteeing a true measurement of the particle diameter without assumptions.

Advantages of Dynamic
Image Analysis
For accurate characterization of non-spherical particles, two-dimensional shape information is essential. Differences in shape may not be reflected in the particle size distribution. Dynamic Image Analysis uses digital video microscopy to capture optimal particle images for processing. Acquired images are processed using sophisticated image analysis procedures and/or are stored for later processing.

A range of accessories is available to adapt the
Eyetech to any application. The materials are analysed closest to their
original state, rather than adapting the nature of the sample to the
instrument.
