BELSORP-mini X - BET surface area, porosimetry and sorption measurement.

The BELSORP-miniX volumetric physisorption instrument for Surface Area and Porosity analysis

BELSORP-miniX gives reliable, rapid, accurate sorption measurements on multiple samples. Building on the successful BELSORP mini II, the mini X offers :

  • BET Analysis, Langmuir surface area,
  • Sorption isotherm measurements
  • Pore size measurements
  • 3 or 4 samples
  • Dedicated P0 port, continuously measured.
  • GDO auto dosing allows highest throughput.
  • AFSM™ for accurate handling of gas free space quantification.

BELSORP-miniX is perfectly adapted for:

  • Surface area by traditional (BET, Langmuir) or DFT methods.
  • Physisorption analysis of porous and powder materials:
  • Meso-porosity analysis.
  • Nitrogen, Argon, CO2, and other non-corrosive gases.
  • Nano-, micro–porosity analysis with CO2 at 0 °C.

Precise physisorption measurement

Dedicated dosing manifold and pressure transducers for each cell allows measurement of the adsorption process in the smallest possible volume to maximise sensitivity and enhance throughput.

Direct measurement of free space during the whole experiment by AFSM® eliminates artefacts due to incorrect and fluctuating cold-zone corrections/compensation.

Software

  • Full MiniX experiment configuration and instrument control software is supplied
    • Provides complete control of automatic sorption measurements
    • Clear display of measurement progress
    • Automatic SystemTest mode for self-diagnosis. Manual control mode for troubleshooting.
  • Independent BELMaster data analysis and modelling for online and offline data treatment in the lab or in your office. The comprehensive library of data analysis models includes all of the models you expect, including :
    • Surface area (single and multi-point B.E.T., Langmuir, STSA, t-plot, alpha-s, DR),
    • Pore size (BJH, DH, DA, MP, HK, SF) with their corresponding surface area values,
    • NLDFT, GCMC simulation.
    • …and much more.

Sample pretreatment

We have a range of options for sample preparation and degassing, both manual and automatic. Please contact us for details.


For your most demanding measurements, you might also like our BELSORP-max-II instrument, for low pressure measurments, condensable species, and a variety of temperature ranges.
