Sensors For Laboratory and Process Applications

Laser diffraction

HELOS | Particle size analysis in laboratory

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. A great variety of dispersing and dosing units provides a flexible adaptation to myriads of industrial and research applications.

MYTOS & Co. | Particle size analysis in process environment

MYTOS integrates the core particle size technologies of HELOS laser diffraction and RODOS dry dispersion in a single robust body: a process-proven laser diffraction sensor for dry powders ranging from 0.25 μm to 3,500 μm. In combination with the sampling system TWISTER a complete in-line integration into the processing pipe is realised. Alternatively, MYTOS may be operated on-line either with TWISTER, MIXER, L-probes or existing sampling solutions. Integrated at-line operation in automated lab environments is succeeded with vibratory feeder VIBRI.

Dynamic Image Analysis

Process-related particle size and shape characterization is realized with integrated image analysis sensors PICTOS, PICTIS & PICCELL covering a size range from 1 µm to 10,000 µm. PICTOS integrates QICPIC dynamic image analysis and RODOS dry dispersion technology in a robust body, which was specifically developed for on-line applications. PICTIS combines image analysis and gentle gravitational disperser GRADIS, allowing at-line or on-line applications in process environments. And PICCELL with its flow-through cuvette finally transfers wet dispersion to on-line operations of image analysis.

Ultrasonic Extinction

The lab instrument NIMBUS analyses manual samples from 300 ml to 1,000 ml in an easy and comfortable way. The compact system uses the OPUS-technology and consists of identical core components. Therefore the same measuring range from below 0.1 µm to 3,000 µm applies to the instrument. Lab applications are found e.g., in petroleum engineering during the analysis of oil sands or in anode production for aluminium smelting (characterisation of anode grade coke in liquid pitch).a

The ultrasonic extinction sensor OPUS analyses both the particle size distribution and the concentration of disperse phases in suspensions and emulsions in the range from less than 0.1 micron to 3,000 microns in real time. OPUS is designed as a stable process probe for high temperatures and pressures and can withstand chemical and mechanical stresses. In addition to a dustproof and splashproof IP65 version, OPUS is also available as an ATEX probe. The connection to various processes is via a selection of process adapters. The common communication protocols are available for the exchange of data with your process control system.

Dynamic light scattering

NANOPHOX | Particle size analysis and stability of nano suspensions in laboratory

NANOPHOX CS opens up the analysis of the size of nanoparticles with photon cross correlation spectroscopy (PCCS) in turbid suspensions and emulsions in a size range from 0.5 nm to 10,000 nm at up to a hundred times higher solid contents than with conventional DLS instruments. The size analysis is independent of the concentration. Typical applications are e.g., pharmaceutical emulsions, oxides, paints, lacquers and inks as well as the research of nanomaterials in general.
