BELSORP-MR1 for BET surface area measurement.

The BELSORP-MR1 single point BET surface area analyser

BELSORP-MR1 gives extremely fast single-point BET measurements by the flow-adsorption method.

The BELSORP-MR6, below, automates the whole process, for the highest productivity.

The single point BET measurement

  • The sample is loaded into a sample u-cell and degassed on the built-in pretreatment station.
    • A constant flow of Nitrogen gas and programmable temperature heating oven dry the sample.
  • The user transfers the cell to the analysis station.
  • A constant flow of 30 % mixed N2 in helium is established
  • The analysis is launched, with measurement of the amount of gas removed from the flow during cooling to 77 K temperature, and during heating up to ambient temperature.
  • The user selects calibration mode to send a calibrated volume to the detector, giving a direct measurement of the sensitivity.
  • The specific surface area is displayed.
  • Full details of the measurement can be copied to a USB key for analysis or archiving.

The BELSORP-MR6

 The high throughput BELSORP-MR6 BET surface area analyser has six sample positions, which are pretreated and measured under automatic control

BELSORP-MR6 has 6 sample positions.

Pretreatment (purging, heating and cooling) runs in parallel with adsorption and desorption measurement.

Analysis time for each sample can go down to 10 minutes.

Optional modules give :

  • full multipoint capability, with a variable-composition gas mixer
  • increased accuracy with P0 measurement
  • continuous measurement, with automatic LN2 filler.

For your more demanding measurements, you might also like our BELSORP-mini-X instrument, with the ability to use different gases, temperature ranges, and for full adsorption characterisation.

We have a whole range of instruments for different types of surface area and porosity measurements by gas sorption. Veuillez nous contacter pour des détails.
