Microtrac MRB's BELSORP MAX X – Compact high-end adsorption solution

Do you want to perform high-quality analyses, but sample numbers never seem to go down? Increase throughput with a flexible instrument that offers unmatched precision coupled with a small footprint. This high-precision gas / vapour adsorption analyser can measure up to 4 samples over a wide range of pressures & temperatures.

BELSORP MAX X covers a broad array of analysis capabilities from specific surface area, pore size distribution, gas, and vapour adsorption to chemisorption. The analyser combines high-precision pressure transducers (133.3 kPa, 1.333 kPa, and 0.0133 kPa) with hard-sealing pneumatic valves and metal gaskets. It also has superior technology to minimize gas leakage and enable ultimate vacuum levels.

The temperature in the BELSORP MAX X is carefully controlled using state-of-the-art technology, from the heated manifold block (50 °C, optional 80 °C) and air bath to the sample, while electropolished gas / vapor lines prevent surface wetting and corrosion.

Additionally, the new BELCONTROL operation software facilitates understanding of the structure and durability of materials through cyclical stability analysis, improves measurement and maintenance efficiency, and sends measurement results via e-mail – all resulting in maximised sample throughput. BELMASTER is the dedicated analysis software for advanced material evaluations. This instrument complies with ISO 9277, 15901-2 and 18852 and can be used for various material morphologies, such as moulded bodies, pellets, and fine powders.

Rather than attempting to control the approximate level of liquid coolant, the BELSORP MAX X uses an innovative method of continuously monitoring free space variations in a reference cell - Advanced Free Space Measurement (AFSMTM). This has been proven to provide greater measurement accuracy. It accurately compensates for free space fluctuations due to environmental factors such as:

• Changes in LN2 level
• Changes in temperature and pressure in the atmosphere
• Changes in coolant temperature due to dissolution of oxygen

Inside the BELSORP MAX X all gas lines, gauges, etc. are installed in a thermostatic air chamber (50 °C) covered with thermally insulating material. The fully temperature-controlled instrument prevents vapor condensation effects and allows various vapor adsorption measurements to be made. It includes measurements with organic vapours up to 40 °C (standard instrument; HT model up to 70 °C). The evaluation of hydrophilicity / hydrophobicity and the measurement of VOC adsorption capacity are further application possibilities.

The multi-sample mode allows the user to obtain adsorption / desorption isotherms of up to four samples simultaneously, while the saturation vapour pressure is determined at any time via a dedicated port. Unlike the high precision mode, the calculation of the free space change in the sample tube is based on a pre-loaded measurement file. This mode is recommended for applications such as quality control, when samples were already characterized in large quantities.
