Bet surface area analysis as a service

We are happy to perform a BET surface area analysis in our lab with your sample. Our analysis service also presents the opportunity to convince yourself of the performance and accuracy of our devices.

BET-Analysis

The measurement is based on the N2-absorption of porous solids at low temperature. Based on the absorbed volume the specific surface of a sample in m²/g can be established. The measurement is taken following the norm DIN ISO 9277 (volumetric principle).

A few examples for suitable samples and materials: 

  • Catalytic converters  
  • Active carbons
  • Porous solids 
  • Ceramics
  • Powders
  • Metal powders

Requirements for samples you would like to submit: 

  • Minimum amount of material: 5 g 
  • Substance must be granulated

We determine the surface area of your sample via single- and multi-point measurements with N2 30% / He 70%.

Please provide us with as detailed information as possible on the material. If available please send a full spec sheet. If you are looking for a comparative measurement please be so kind as to send us the surface area values from earlier measurements. 

The surface area analysis is performed with Macsorb-BET-Surface-Analysers for which Probst & Class is the exclusive distributor in Europe.
