Particle Characterisation


Precision Laser Particle Sizing made Simple


The ANALYSETTE 22 NeXT from Fritsch provides precise measurement of particle sizes with minimal training requirements - even for employees with no prior knowledge. Whether in production and quality control, research and development, in the lab or for incoming and outgoing goods inspection, its robust mechanics are an additional advantage. A brief introduction to the instrument is sufficient; the rest runs automatically.


To start a measurement with the ANALYSETTE 22 NeXT, simply select one of the predefined Standard Operating Procedures (SOP). The software sets the necessary instrument parameters automatically and prompts you to add the sample material. As soon as the quantity is sufficient, the measurement starts automatically. First the automatic dispersion takes place, the automatic measurement follows and also the evaluation of the analysis results is done automatically. After the automatic rinsing the automatic report with cleary organised results is provided.


The ANALYSETTE 22 NeXT Micro has a measuring range of 0.05 - 1500 µm and is suitable for all typical measurement tasks. The high-end ANALYSETTE 22 NeXT Nano has an extra wide measuring range of 0.01 - 3800 µm with an additional detector system that provides maximum precision and sensitivity for smallest particles.


Advantages include extremely easy operation and cleaning, reliably reproducible analysis results mostly in less than 1 minute, and the recording of additional parameters such as temperature and pH value during wet dispersion.

The Power of the Probe: Dynamic Light Scattering Made Easy


Rapid, simple and reliable particle size measurements in suspensions and emulsions without using consumables - all this is possible with Microtrac’s unique probe technology used in the Nanotrac analyser series: Nanotrac FLEX and Nanotrac WAVE II. The compact units operate with the Dynamic Light Scattering (DLS) method over a wide concentration range, usually without dilution, to measure particle size, zeta potential, concentration and molecular weight.


Thanks to the unique, flexible probe design and the use of laser-amplified detection in the Nanotrac FLEX, any suitable vessel can be turned into a sample cell. For Nanotrac WAVE II, a wide selection of measurement cells is available. This design enables sample measurements without dilution and without prior knowledge about the particle distribution, based on the Frequency Power Spectrum (FPS) method instead of classic Photon Correlation Spectroscopy (PCS).


The revolutionary fixed optic design of the Nanotrac FLEX probe allows for measurement, for example, in 1.5 ml Eppendorf Tubes® down to one single droplet. As any vessel can be turned into a measurement vessel, the probe can be used at-line as well as in-line to monitor particle growth during a reaction.

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.”

Multi Detector Characterisation of Polymer Nanogels


Testa Analytical Solutions eK reports how researchers at Lodz University of Technology have combined the advanced analytical capabilities of its GPC/SEC triple detection system with a BI-200SM light scattering goniometer to derive in-depth information about an exciting new generation of polymer nanogels.


Testa Analytical Solutions has developed a range of highly sensitive detectors (Viscometry, DRI, UV, MALLS, Flowmeter) that can be used as part of a triple detector GPC/SEC system to determine the size and conformation of all types of synthetic polymers, biopolymers, proteins, and peptides. The company is also able to offer polymer researchers - the Bl-200SM light scattering goniometer - a precision research grade instrument designed for precise and accurate measurements. Based on a special turntable with precision ball bearings and stepping motor, the Bl-200SM’s modular, automated design and quality construction guarantee precise measurements due to the wobble-free movement of the detector. The BI-200SM can measure light scattering over a wide angular range (8° to 155° with 25 mm cells) and offers fine adjustment of measurement angles to 0.01° directly using a large, fine-control knob or PC-driven motor control.
