Analytical Instrumentation Advanced laser particle analyser with new dry dispersion module
Fritsch’s A-22 laser particle analyser offers simplicity, precision, and versatility in particle measurement. Its minimalist design makes it user-friendly, easy to clean, and low-maintenance, delivering precise results in both the nano and micro ranges in under a minute. Recently, Fritsch introduced a new dry dispersion module to expand the A-22’s modular capabilities.
With a broad measuring range from 0.01 to 3,800 μm, the A-22 achieves maximum accuracy, even with the smallest particles. The device uses a single laser without the need for an additional light source for backscattering. Thanks to advanced electronics and high-resolution converters, the A-22 records signals from all detector elements simultaneously, capturing the full scattered light distribution in real-time. This speed, combined with the unique angled arrangement of the measuring cell to the laser beam, enables the instrument to cover a larger scattering angle range than similar devices. With only one image needed for the entire measuring range, the total process, including cleaning, takes less than a minute for most samples.
Fritsch’s reverse Fourier set-up, a market standard, is used in the A-22. It requires no optical elements between the measuring cell and the detector, minimizing components and moving parts. This compact design contributes to the device’s durability and low wear, making it virtually maintenance-free. Cleaning is straightforward due to its simple construction, with removable parts that do not require tools.
The A-22 software includes predefi ned standard programs for common measuring tasks, ensuring ease of operation. Users can also modify or create their own programs, with automated settings for dispersion, measuring frequency, and intervals, ensuring reproducibility in measurement processes.
The new dry dispersion module allows for measurements of materials that react with liquids and accommodates larger sample volumes. This system uses compressed air to break down agglomerates and measure particle size distribution directly in the laser beam.

Hiden Isochema, a leading manufacturer of sorption instrumentation, has launched the IGA ECOsorp, a ground-breaking benchtop sorption analyser tailored specifi cally for carbon capture research. This state-of-the-art instrument integrates advanced capabilities for co-adsorption of water and carbon dioxide across various carbon capture conditions, positioning it as an essential tool for researchers and scientists in the fi eld.
The IGA ECOsorp combines high-resolution gravimetric water sorption with CO2 gas
sorption under dynamic fl ow conditions, offering an economical and practical solution for evaluating the performance of candidate carbon capture sorbents in a wide range of environmental settings.
“We are thrilled to introduce the IGA ECOsorp to the scientifi c community,” remarked Dr Mark Roper, Sales and Marketing Director at Hiden Isochema. “This cutting-edge instrument underscores our commitment to delivering high-quality, dependable tools
for advanced research. Its unique capabilities will signifi cantly empower researchers to develop and optimise new materials for carbon capture, thereby contributing to global efforts in combating climate change.”
Key features of the IGA ECOsorp include simultaneous measurement of water and CO2 partial pressure range (from 100 ppm to 100%), proprietary barometric compensation technology for precise CO2
sorption, widest controllable CO2 fl ow
regulation, and an advanced thermostat design ensuring long-term stability. The instrument supports complete automation for high-resolution isothermal and extended cycling studies, facilitating detailed method development and analysis. Additionally, it offers fully programmable experimental protocols and in-situ degassing and activation capabilities with an integral heater reaching up to 350°C for sorbent regeneration.
Engineered to independently control carbon dioxide and water concentrations, the IGA ECOsorp enables accurate assessment of material performance under Direct Air Capture (DAC) conditions. It supports fully programmable measurements across temperatures ranging from 5 to 85°C, accommodating in situ degassing and regeneration at elevated temperatures.

The EST-TSHR NEXIS GBM Gasbag Sampling Module provides unsurpassed sample data performance with fast analysis times. It boasts several unique hardware features to make sampling and analysis of non-pressurised gas samples safe, speedy and easy. The NEXIS GBM can be connected to any EST-TSHR NEXIS combustion analysers to analyse total sulphur, nitrogen or chlorine levels in non-pressurised gas samples.
This highly precise and versatile analyser delivers maximum sample volume fl exibility (from 5-500ml) instead of a standard loop fi xed size of 10ml, so it is ideal for both ultra-low and very high concentrated applications. The NEXIS LINK Software provides complete control and operation enabling precision dosing gas sampling.
The NEXIS GBM is compatible for a broad array of atmospheric pressure gasses, so there are no worries about pressures or pressure-related errors. It delivers fast analysis
times of less than 500 seconds for both low and high sample volumes, with a default analysis time of 250 seconds. There are endless opportunities for creating calibration levels and replicates in a single queue run based on one gasbag standard.
This device provides complete digital electronic control for dosing a sample’s specifi c volume and gas injection speed. This also includes extremely accurate feedback providing users with the real injected volume and temperature for each individual injection. The NEXIS GBM also ensures operational safety with Autonomous Pressure Intelligence which monitors the outlet pressure to the analyser continuously and takes the appropriate actions when necessary.
EST-THSR have also included a sensor for detecting hydrocarbon leaks in and around the NEXIS GBM and analyser, as well as a safety purge valve which will operate automatically if and when hydrocarbons are discovered in the NEXIS GBM; the Argon carrier gas will purge all oxidising gasses. An inline particle fi lter defends the Sample MFC against any particles present in the gas streams or in the vicinity of the GasBag - and possibly caught during a sample change.
