Ground powders, mineral suspensions and granular materials play a critical role across industries including chemicals, ceramics, food and specialty materials. Their performance depends on particle size distribution, morphology and particle shape, making accurate particle characterization essential for process optimization, product quality and manufacturing consistency.
Classizer™ ONE, powered by SPES technology, provides non-invasive multiparametric particle analysis for powders dispersed in liquids. The system measures particle size distribution, particle concentration, effective refractive index and particle aspect ratio without relying on complex inversion algorithms, enabling reliable characterization of highly polydisperse and non-spherical mineral samples.
The case of quartz
Quartz particles are often irregular and non-spherical, making conventional particle sizing less reliable. SPES technology compares the measured effective refractive index with the expected bulk value while analysing EOS CLOUDS distributions to evaluate particle shape, sample homogeneity and deviation from ideal spherical behaviour.
EOS CLOUDS visualization highlights the optical fingerprint of quartz particles and demonstrates how SPES technology identifies deviations caused by non-spherical morphology. The combined analysis of refractive index and particle distribution delivers more representative characterization than particle size alone.
The case of kaolinite
Kaolinite particles exhibit complex plate-like morphologies that strongly influence optical behaviour. SPES technology accurately characterizes these non-spherical mineral particles by combining particle size, effective refractive index and optical properties, providing reliable information for quality control and material development.
The EOS CLOUDS map reveals the characteristic optical distribution of kaolinite particles, allowing accurate assessment of particle morphology, refractive index and sample heterogeneity even when particle shape differs significantly from an ideal sphere.
