Substance characterisation

Technological solutions built on four decades of intensive research

Using Topas preparation technologies and analytical instruments for disperse material systems (suspensions, powders, emulsions), a wide variety of physico-chemical properties can be determined for substance characterisation. These include, among others, the deagglomeration behaviour, the particle size distribution, the particle concentrations or the coarse fraction. These characteristics are used, among other things, in development, quality control or safety data sheets in accordance with the REACH Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals). Sample fractionation of an analytically more precise evaluation is a further field of application. Contact us – together we will find your solution.

 

The Topas laboratory on your desk: modular and smart preparation and analysis technologies

Preparation technologies from our company include ultrasonic disintegrators, vibrating screen exciters for microsieving, dry dispersion or bulk solids analysis. We also show diversity in our spectrum of analytical instruments such as liquid particle counters, sedimentometers, aerosol spectrometers or pore size measurement systems.

 

For more than 30 years, customers from a wide range of sectors have learned to rely on our strengths:

  • industry (quality controls for incoming and outgoing wares)
    • chemical, biological, medical
    • semiconductor industry
    • automotive industry
    • food industry
    • cosmetics industry
  • research
    • analysis laboratories
    • scientific institutes
    • industrial investigations
  • government agencies
    • environment
    • occupational safety
    • consumer protection
    • meteorology

 

In determine the characteristics of powders and suspensions in the best possible way, a defined and reproducible dispersion is required. The state of dispersion, i.e., particle concentration and particle size distribution, can be analysed by existing measurement technologies but also with our analytical instruments.

We provide you with competent technologies for analytical preparation:

GOOD TO KNOW

40 years of experience in granulometry

As a spin-off from the Technische Universität Dresden, the founders of Topas were already involved in the field of particle size analysis (granulometry) in the beginning of the 1980s. Our FAS 362 liquid particle counter, which is still in use today, is thus one of our first proprietary technologies and impressively demonstrates almost 40 years of experience.
