Specific surface measurement

Analytical methods Physicochemical Specific surface measurement

Service description

The measurement of the specific surface area of ​​a sample is made from an isotherm obtained by nitrogen adsorption / desorption volumetry at 77K. The specific surface is expressed in m2/g of sample after degassing from the BET method. The implementation of the t-plot and BJH methods allows an estimation of the porosity of the sample and its distribution (between 8 and 800 Å of opening).

Materials to provide

• Dry samples
• 3 g per sample
• Initial degassing of the samples at 110 °C under vacuum
Further details on the project may be requested directly by the expert. You will be able to exchange directly with the experts after filling in the form below.

Delivrable(s)

  • Determination of the specific surface area with the BET method
  • Determination of microprosity and mesoporosity if required
  • Excel chart data
  • Detailed report and experimental curve
  • Study following the specifications validated with the Expert
