HELOS - a powerful technology for particle size distribution analysis

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 by Sympatec, specializing particles analysis before all. A size ranges from below 0.1 µm to 8,750 µm is mastered. The modular sensor reveals its true superiority when operated with feeding and dispersing systems, that guarantee for best adaption to the product sample. Optics match ISO 13320 fully. The system match FDA 21 CFR part 11 requirements.

Dispersion modules

RODOS/L – This reliable dry dispersion module determines the validity of the size analysis – especially for collectives of fine, dry and cohesive particles. The principle of RODOS dry dispersion with an upstream dosing unit and a powerful compressed air injector ensures the effective and product-specific dispersion of solid particles in a size range of less than 0.1 microns to 4,000 microns. Dosing initially generates a constant mass flow. Subsequently, dispersion forces tailored to the product ensure an effective separation of the particles that are fed to the sensor in the aerosol jet as single particles. This is achieved just as reliably for fine, highly agglomerated particles as for the gentle dispersion of metastable and coarse particles.

QUIXEL – QUIXEL is the advanced wet dispersing system suitable for particle size analysis on all kinds of suspensions and emulsions in the size range of 0.1 µm to 3.500 µm. Its innovative, tubeless design enables very fast measuring cycles. Even high-density particles such as 3 mm ball bearing beads made from stainless steel are safely transported in water through the flow through cell without the need for using special liquids of high viscosity. The wet dispersion process is supported by a built-in ultrasonication unit, which is adjustable by software from 0 to 60 W in 1% steps.

SUCELL – SUCELL is an automated wet dispersing unit for particle size analysis of all kinds of suspensions or stable emulsions in the size range of 0.1 µm to about 875 µm. It operates in a closed loop and can be used with all sensors of the HELOS family.
