Fast and Reproducible Particle Analysis with Versatile Dry Dispersion
Laser Diffraction | Particle Size and Size Distribution from < 0.1 µm to 875 µm

The proven HELOS laser diffraction series – with its classical parallel beam laser diffraction set-up – in combination with the fully automated RODOS dry disperser offers a powerful technology for reliable particle size distribution analysis of fine dry, even cohesive powders.

In the early 1980s, 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 our 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).

Dosing is performed via the precision vibratory feeder VIBRI/L, which guarantees optimum concentration of the sample in the measuring zone with a uniform, controlled product supply. The perfectly coordinated combination of sensor, dosing and dispersion enables a gentle, product-specific and precise particle size analysis far into the submicron range. All measurement and dispersion parameters are software-controlled. The intuitive and versatile PAQXOS software guarantees fast measurement sequences and presents meaningful results in customisable graphs and tables.

The modular HELOS system design allows this configuration to be systematically expanded with a great variety of dispersing and dosing units, thus opening up a wide range of industrial and research applications.
