Story HELOS & RODOS & Co. - analysis of particle size and particle The proven HELOS series – with its classical laser diffraction set-up deploying a parallel beam – offers a powerful technology for particle size analysis of powders, granules, suspensions, emulsions, sprays and numerous other disperse systems from below 0.1 µm to 8,750 µm. HELOS | RODOS & Co. | Particle Size and Particle Size Distribution Analysis with Unequalled Precision and Accuracy The proven HELOS series 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 precondition for convincing and reliable measuring results are based upon product-adapted and reproducible sample analyses. A product adaption will be achieved if particle collectives are dispersed and supplied to the measurement in their original condition: dry powders and granules, suspensions and emulsions wet, as well as sprays and inhalants as aerosols – without time-consuming preparations. 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. All measurement and dispersion parameters are software-controlled and can be saved as retrievable measuring methods (Standard Operating Procedures (SOPs)). In this way, measurements are reliable and independent of the operator, even if the product and application are changed frequently. 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. Our particle size analyser HELOS sets new benchmarks for precision and accuracy. 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 and more powerful evaluation modes (FREE & MIEE).
