What the BELSORP MR 1 is
The BELSORP MR 1 is a compact, stand-alone analyzer for specific surface area by the dynamic single-point BET method. A gas mixture of known concentration — for example 30 % nitrogen in helium — flows over the sample while it is cooled with liquid nitrogen. A thermal conductivity detector records how much nitrogen the sample takes up and then releases again when the Dewar moves down; the sharper desorption peak is integrated to calculate the surface area.
Pretreatment of one sample and measurement of another run at the same time. The Dewar moves automatically, a calibration function is built in, and the instrument is operated from a touch panel. The surface area is displayed as soon as the measurement ends, without manual calculation, and results can be saved to a USB stick.

What it tells you about a powder — and what it does not
The MR 1 answers one question quickly: what is the BET surface area of this sample? The datasheet names catalysts, battery materials, zeolites, ceramics, carbon, cement, silica, pigments, toners and pharmaceuticals among its fields.
| BET specific surface area | single-point value from 0.01 m²/g, repeatability within ±1.0 % |
| Lot comparison | the same method and number for every lot, displayed without manual calculation |
| Throughput | approx. 15 minutes per measurement while the next sample is pretreated |
| Low-area samples | krypton as adsorbate instead of nitrogen |
| Not reported | adsorption isotherm, pore size distribution, pore volume — these need a volumetric analyzer |
How a dynamic-flow measurement works
Where the MR 1 stops — and what to take instead
The MR 1 measures single-point BET surface area of one sample at a time — nothing more. It does not record an adsorption isotherm, so it gives no pore size distribution or pore volume, and single-point BET is not the method for microporous materials. For multi-point BET and mesopores on up to four samples, take the BELSORP MINI X. For micropores and krypton BET down to 0.0005 m²/g, the BELSORP MAX G or the BELSORP MAX X. Pores above 500 nm need mercury porosimetry on the BELPORE, and true density the BELPYCNO gas pycnometer.
