In course of our analytical service we provide the performance of following measurements:

Adsorption (gravimetric)

  • Adsorption and desorption
  • Pressure range from vacuum to high pressures up to 40 MPa
  • Measurement temperatures between -20°C and +350°C
  • Pure gas measurements (e.g. CH4, N2, CO2, H2, H2S, CO, other on request)
  • Gas mixture selectivity measurements

Adsorption (volumetric)

  • Cost-efficient, time-saving
  • Screening of several sorbent materials
  • Simultaneous measurement of up to 5 different materials
