Malvern Mastersizer 3000 particle size analyser

The Mastersizer 3000 is a laser diffraction particle size analyzer that can measure particle size distributions for both wet and dry dispersions. It is capable of measuring particles from the nanometer to millimeter size ranges.

The system in the NRF has Aero S and HV

The Aero S is a completely new dry powder disperser developed using state-of-the-art powder dispersion understanding. Modular in design, it is easily configured for different applications, delivering efficient sample dispersion for both robust and fragile materials.

  • Standard disperser suitable for both cohesive and fragile particle measurements.
  • Impaction systems available for robust material dispersion.
  • Precise dispersion pressure control, to ±0.1 bar delivers outstanding reproducibility.
  • Range of sample feed trays and hoppers enable measurement of different sample volumes.
  • Enclosed cell delivers bias-free measurements whilst minimizing user exposure to the sample.
  • Full software control of all measurement functions, including sample feed and dispersion.
  • Ceramic dispersers available for abrasive materials.

Surface Area Analyser

 

Micromeritics Gemini VII BET surface area analyser

Micromeritics’ Gemini VII 2390 Series of surface area analyzers r produces accurate and repeatable surface area and porosity results. 

During an analysis, differential pressure between reservoirs is monitored. This common mode technique assures that any differential pressure is solely due to adsorption by the sample and not to factors that lead to variations in free space during an analysis.

  • Permits low surface area measurements without requiring krypton by essentially eliminating free-space error, the limiting factor in typical static volumetric systems
  • Accelerates delivery of the analysis gas because sample uptake controls the rate at which the gas is delivered to the sample. This results in a surface area analyzer that is as fast as the physics of adsorption allows
  • The use of a servo valve to control the rate of gas flow into the sample tube assures accurate attainment of target pressures without pressure overshoot
