New Automatic Dispersing System for Particle Shape and Size Analysis
The proven Particle Sizer ANALYSETTE 28 ImageSizer from Fritsch, in combination with the new automatic and powerful wet dispersion is especially suitable for fine particles, poorly flowing, fine-agglomerating or sticky materials that do not react in water or other liquids.
For perfect dispersion the sample material is fed into a closed liquid circulation system and is pumped with high power through the measuring cell between camera and LED strobe light. The continuously obtained images are the basis for the analysis with a variety of evaluation possibilities.
For wet measurement, choose from 3 different bi-telecentric lenses for optimum adaptation of the total measuring range from 5 μm to 3 mm to your measuring task. In combination with the powerful industrial camera, they guarantee the highest accuracy of the imaging of each individual particle always at the same imaging scale and the highest shape accuracy with the greatest possible depth of field.
The first fully automatic wet dispersion unit that does completely without valves and moving seals in the sample circuit and for emptying the system. This makes it significantly more robust and virtually wear-free. And there are no hard-to-clean dead spaces in which dirt can become permanently lodged.
If you frequently measure sample material that tends to agglomerate, you can additionally connect a powerful ultrasonic box to the wet dispersion unit. It enables an even finer adjustment of the wet dispersion to the respective sample material.

High-performance Characterisation of Next-generation Adsorbents
The Breakthrough Analyzer (BTA) from Micromeritics Instrument Corp provides precise characterisation of adsorbent performance under process-relevant conditions. Combining Micromeritics’ expertise in gas adsorption with its microreactor and pilot plant technology, the BTA delivers reliable, selective adsorption data for gas/vapor mixtures. A highly efficient tool for evaluating the performance of next generation adsorbents, the BTA is particularly valuable for researchers working in fields such as gas separation, storage and purification, carbon dioxide capture and energy storage.
Incorporating patented high performance blending valves, precision mass flow controllers and optional vapour sources, the resulting gas delivery system has minimal dead volume and ensures the precise control of both composition and flow rate. Adsorbent is held in a column that uses only 0.05 - 2.5 g of sample per measurement. A thermostated environmental chamber provides accurate, uniform temperature control of all components, up to 200°C, with no cold spots. Automated sample activation and adsorption studies can be performed at temperatures up to 1,000°C with the precise resistance furnace. Sequenced and cyclic experiments are easily programmed. Operating pressures can be controlled from atmospheric to 30 bar via a back-pressure valve. The gas detection system and other features are readily customised for the application(s) of interest.
Jeff Kenvin, the Vice President of Science for Micromeritics stated: “The new BTA is a compact, safe, fully-automated bench top system enabling scientists and engineers to generate the highest quality breakthrough curves. Precise and reproducible data can be obtained using small sample quantities; easily outperforming competitive systems. A wealth of adsorbent studies can be conducted including mixed gas studies, competitive sorption assessments, and high-pressure isotherm generation. BTA users will accelerate new adsorbents from discovery to commercial use, faster than ever.”

A New Dimension in Particle Analysis
The Microtrac MRB SYNC Analyzer provides traditional users of laser diffraction technology with exciting new capabilities to characterise their materials. The proven tri-laser technology provides accurate and repeatable laser diffraction information from light detected over 163 degrees of angular scatter. When combined with state-of-the-art camera technology capturing images of the particle stream at the same time, the SYNC offers not only size data but significantly more information about the shape of the materials and the quality of the dispersion.
The patented Synchronous measurement technology of the SYNC allows users to make both a laser diffraction measurement and an image analysis measurement on a single sample, in the same sample cell at the same time: One sample, one optical bench, one flow path, one sample cell, one integrated GUI, one analysis.
This makes the SYNC ideally suited for both routine QC and research applications; it provides valuable information to researchers as they develop new materials and processes. The powerful software interface offers both particle size distribution information as well as a multitude of morphological parameters. The patented BLEND routine allows users to examine materials over a wide size range from 0.01 microns to 4000 microns.
