We have expanded our laboratories space and now we have 3 working labs in our building on Ballycoolin Road in Dublin.

These labs are open for visitors for the purposes of doing instrument demonstration and running customers’ samples:

 

Lab 1 – a standard demonstration lab for most wet or liquid sample analytical instruments eg particle sizing, rheology

Lab 2 – a dedicated powder analysis lab for dry powder samples

Lab 3 – a full service lab for testing incoming equipment and instrument engineering
 

 

 

 

 

 

UPT – novel cost-effective powder testing

Friday, April 1st, 2016

Freeman Technology, global leader in powder testing technologies, have introduced the Uniaxial Powder Tester (UPT). This is the world’s first stand-alone uniaxial tester for simple, sensitive and cost-efficient powder characterisation. This new tester delivers automated, highly repeatable measurement and provides a cost effective alternative to traditional powder testing techniques.

Uniaxial testing involves the construction of a consolidated powder column, which is then fractured through the application of a vertical stress to directly measure Unconfined Yield Strength and Flow Function of powders.

The UPT is available in either manual or advanced version. Read more…

University of Manchester studied Metal-Organic Framework (HKUST-1) for CO2 capture from flue gases

In the recent study by The University of Manchester, HKUST-1, one of the extensively studied Metal-Organic Framework (MOF) for gas separation, was evaluated as a model material for CO2 capture from flue gas stream.

Flue gases contain percentage of CO2 of 5-15%, N2 70-75%, and water vapour of 5-7%. HKUST-1 behaviour was studied with these gases at conditions similar to those of flue gas emission at temperature of 50-75?C. The synthesis was first improved in terms of gaining high production yield and suppressing the by-product formation. According to Nadeen Al-Janabi from The University of Manchester, “The synthesised samples showed good CO2 capacity in comparison to N2. While, the hydrothermal stability test (water vapour adsorption) showed that HKUST-1 in its current form is hydrothermally instable neither at high temperature nor at room temperature. The outcome is to modify the structure of HKUST-1 to enhance its hydrothermal stability otherwise it cannot withstand humid flow such as that of flue gas. To assess the moisture stability of HKUST-1, the water vapour adsorption was measured using DVS 1 “Surface Measurement Systems”.

Highlights:

  • Improved hydrothermal synthesis of HKUST-1 at 100?C with the yield up to 89.4%.
  • Evaluation moisture stability of HKUST-1 under relevant flue gas adsorption conditions (45–60?C, 0–1 barG).
  • Interpretation of decomposition dynamics of HKUST-1 under humid conditions.
  • Aggregation of water molecules near copper centres can displace the BTC ligands leading to the decomposition of HKUST-1.

Graphical Abstract

The study was performed by a group from the School of Chemical Engineering and Analytical Sciences, The University of Manchester and Department of Chemical Engineering, University of Bath. It was presented at the 13th International Conference of Carbon Dioxide Utilisation in Singapore and has won several awards and recognition. A second paper in connection to this study is about to be released soon.

Vision technologies for material characterisation

Tuesday, July 21st, 2015

Why use vision products?

With the prevalance of fast, automated particle size analysers like Malvern Mastersizer you get reproducibility, repeatability, size distributions and statistics. So do we need Vision systems at all?

The answer is yes, but not instead of Mastersizer and for the following reasons:

  • Image evidenvisionce can support or explain the results summarised in your distribution statistics. If you have change of size its important to confirm what’s happening with photographs.
  •  Only an imaging system gives you detailed shape information. And shape is important to the bulk properties of a powder. Shape with particle size and powder flow characteristics (Freeman FT4) give you the full picture.
  • You can add Raman to your vision system and gain useful spectroscopic information of the individual particles. With a static analyser like Morphologi G3-ID you can move back to noted particles and capture their spectra after imaging all the particles!
  • Fast camera optics can study changes in a dispersion or in a sample with treatment in real time. Dynamic vision systems like Hydro Sight can shorten method development times and resolve technical issues.
