Particle analysis

Nowadays particle analysis is essential in many fields. Powder granulometry is a must know if one is to control perfectly a production process. Cement or ceramic properties depend on the distribution of particle size. There are numerous examples in many fields : cements, ceramics, mineral, pharmaceutical, geology, paintings, ink, petrochemical industry… The Zeta potential is a second parameter enabling to anticipate the particles behaviour in an environment, and notably its stability. Finally, the morphological analysis enables it to complete an analysis and to explain powders behaviour, or a powder intification during medico-legal analysis.

Granulometer

The analysis of particles size distribution is an essential data to forecast the powder behaviour in a process, or its physical properties (cement, ceramic, toner...). Two complementary technologies enable the particle analysis from a few nanometers to 2 mm : > The laser diffraction enables fast and reliable analysis from 20nm to 2mm, adapting to the different types of samples thanks to a full range of accessories: dry way, liquid way, small and wide volumes. > The DLS (Dynamic Light Scattering) will enable the particle analysis of some nanometers. This technology is often combined with the Zeta potential analysis.
Zetameter

The Zeta potential is a parameter which describes the interaction between a particle and its environment. Doing so, it enables to anticipate a suspension or an emulsion stability. A Zeta potential having a high absolute value will indicate a stability, while low values will be the sign of instability. Applications are very diversified : food industry, biotechnology and medical (proteins), pharmaceutical, ceramic, wastewater treatment plant, mining...
Rehometer

Rehology consists in the study of fluids flow and solids distortion when subjected to constraints or distortions. The rehological properties measurment helps to developed a better product, anticipate its physical properties during and after the production and anticipate its performances during its consumption. We have several types of rehometers with control capacities of the constraint and of the distortion adaptable to your need. According to your applications, we will propose you the most adapted solution. In order to provide you with the best equipment on the market , HTDS selected MALVERN solutions. For more details and an offer adapted to your problematic contact us.

Particle morphological analysis

If the size and distribution analysis enable to characterize quickly and reliably a powder, they don't give any information on particles shape. though, particle morphology is also an important parameter to explain a physical behaviour or a physical property. A microscopic analysis enables to visualize some particles, but no operator will analyse enough particles to obtain a representative analysis. With the morphological analysis instruments of our range, you will obtain accurate, reliable and representative results thanks to the automation of the sample preparation and analysis. In order to provide you with the best equipment on the market , HTDS selected MALVERN solutions. For more details and an offer adapted to your problematic contact us.
