A lot of Science in a little space: BELSORP MAX X. High-End Adsorption. Smallest Footprint. Unrivaled Performance.
Microtrac's BELSORP MAX X is the latest model in the BELSORP MAX series, featuring a more compact design and lower weight. This high-precision gas / vapor adsorption analyzer can measure up to four samples over a wide range of pressures and temperatures. BELSORP MAX X covers a broad array of analysis capabilities from specific surface area, pore size distribution, gas, and vapor adsorption to chemisorption.
Combining high-precision pressure transducers (133.3 kPa, 1.333 kPa, and 0.0133 kPa) with hard-sealing pneumatic valves and metal gaskets, the analyzer has superior technology to minimize gas leakage and enable ultimate vacuum levels. 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 maxXimized 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 molded bodies, pellets, and fine powders.

AFSMTM: Highest Reproducibility Available on Any Adsorption Instrument
Rather than attempting to control the approximate level of liquid coolant, our innovative method of continuously monitoring free space variations in a reference cell – Advanced Free Space Measurement (AFSMTM) – has been proven to provide greater measurement accuracy. It accurately compensates for free space fluctuations due to environmental factors such as:
Vapor Adsorption Option
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 vapors 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.
Extensive Product Range
BELSORP MAX X is available in different models for a wide range of applications. Microtrac offers the perfect solution for each customer's individual needs.
Gas Selector for Different Adsorbents
Three gas ports (corrosion resistant) are available in the standard configuration. To expand one standard line to four gas lines, a gas seector can be addded. The gas lines can be expanded from 3 to 6, 9 and 12 lines.
Measurement Temperature Control
Dewars, water baths and heaters are available covering a wide range of measurement temperatures. The heater can be used for measurements as well as for sample preparation.
The BELSORP MAX X HT is a special model enabling various types of vapor adsorption (water vapor, VOCs, and more) at higher temperatures than the regular version. The manifold block can be heated up to 80°C, enabling a wider application range under more realistic conditions. The instruments is used in application fields such as:
The BELSORP MAX X HP has been added as a custom solution to the BELSORP MAX X product line to enable gas adsorption, BET surface area, pore size distribution, vapor adsorption, and the evaluation of adsorption rates at high pressure up to 900 kPa. The instrument is used in application fields like:
BELSORP MAX X offers four independent ports and one dedicated port for saturated vapor pressure measurement. Up to three ports are equippable with a unique set of pressure transducers (0.0133 kPa, 1.33 kPa, 133.3 kPa) for better micropore analyses, allowing fully independent and simultaneous measurements over a wide range. Two measurement modes can be selected depending on the application. The High Precision Mode and the Multi-sample Mode are both available for measurements starting at lowest relative pressure P/P0 = ~10-9.
The high-precision mode allows the simultaneous acquisition of adsorption / desorption isotherms for up to three samples. The fourth port uses an empty sample cell as a reference for the precise measurement of free space/dead volume changes (patented AFSMTM technology). In addition, a special port allows accurate measurement of the saturation vapor pressure at any time. This mode is recommended for research and development purposes, e.g. for evaluating small sample volumes in material development.
The multi-sample mode allows the user to obtain adsorption / desorption isotherms of up to four samples simultaneously, while the saturation vapor 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.
The two following features reduce the measurement time by about 50-70%:
By uploading a previously measured adsorption isotherm, the optimum measurement conditions for the samples are automatically determined. Each measuring point can be conveniently added or deleted, allowing the user to easily determine the gas injection quantity.
By determining the gas inlet pressure according to the installation environment (secondary pressure of the gas cylinder) before measurement, the control valve is automatically optimized for speed and performance, successfully reducing the measurement time.
Various gas and vapor adsorption measurements are possible. With dedicated accessories, a wide temperature range can be maintained during analysis or pre-treatment.
Measurements can be made on a variety of materials, including pellets, molds, substrates, as well as powders and other materials that should not be exposed to the atmosphere. The connector is equipped with a sample tube with an outer diameter of φ9 mm or φ14 mm. Special sample tubes can be provided for larger samples, such as pellets, and smaller fine powder samples can also be easily measured with the appropriate sample tubes.
The versatility of BELSORP equipment is truly world leading. The numerous features and capabilities are complemented by BELCONTROL the intuitive and user-friendly operation software. It guides the user step-by-step through the analysis process. This includes the setup of analysis conditions, executing the measurements, when to fill and setup the liquid nitrogen or other bath, when to replace the gas cylinder, the degassing steps, and much more. The software is designed to make the instrument accessible and operable to everyone, including inexperienced users.
For inexperienced users or for measurements of unknown samples, BELCONTROL only requires basic sample information (name, mass, etc.), pre-treatment conditions (if not performed externally) and the measurement range.
Detailed control of the configuration and measurement settings is possible to optimize the measurement conditions (e.g. dosing settings, equilibrium criteria, leak test option, etc.). This allows the user to fully customize the sample analysis to his needs.

Data can be analyzed by drag-and-drop. Graph overlay, X-Y axis scaling, and unit conversion, point markers, and colors can be easily changed. Color can be set for individual data to improve visibility of the same data across different analysis types. The screen with the analysis results can be saved. Even if the PC is shut down, the analysis can be performed again from the saved state when the PC is restarted. The analysis results can be easily converted to MS Excel format by drag & drop.
The routine analysis setting function is useful when performing the same analysis over and over again. User-defined data can be saved as reference isotherms for pore distribution analysis, t-plot and αs. All operations can be viewed with a single right-click. BELSIM (NLDFT / GCMC) software for pore distribution analysis by simulation is included. Easy conversion to MS Excel is done with just one mouse click.
