Modular laser diffraction sensor for laboratory analysis of particle size and distribution from below 0.1 µm to 8,750 µm

The proven HELOS series – with its classical parallel beam laser diffraction set‐up – offers a powerful technology for particle size distribution analysis of powders, granules, suspensions, emulsions, sprays and numerous other particulate systems. A size range from below 0.1 μm to 8,750 μm is mastered. The modular system design together with a great variety of dispersing and dosing units provides a flexible adaptation to the most diverse industrial and research applications.

Thirty years ago, Sympatec introduced a breakthrough innovation which was leading laser diffraction to another dimension: dry powder dispersion for even the finest, cohesive powders came true with RODOS. And with the R series of laser diffraction sensor HELOS, new benchmarks for precision and accuracy have been achieved. Latest improvements comprise enhanced application of parameter‐free Fraunhofer evaluation down to the submicron regime (below 1 μm), the greatest measuring signal frequency for best resolution with range combination technology and more powerful evaluation modes (Fraunhofer & Mie). Laser diffraction is now even closer to absolute standards. Continually, ISO 13320 requirements and limits are considerably outmatched.
