BELPORE Series

BELPORE Series
Mercury Porosimeter

The BELPORE mercury porosimeter series for low-pressure (LP), medium-pressure (MP) and high-pressure (HP) reliably and reproducibly measures pore diameters from 1mm to 3.6nm.

The knowledge of porosity, pore sizes and pore volume is of fundamental importance for the characterization of porous materials. Mercury porosimetry is the most widely used method for determining the pore size distribution of accessible macro- and mesopores in solids.

The technique is based on the pressure-dependent intrusion of mercury as a non-wetting liquid into a porous material. Using the Washburn equation, the corresponding pore size is calculated from the applied pressure.

Microtrac MRB, as a provider of state-of-the-art solutions in the field of particle characterization and gas adsorption, has now expanded its extensive portfolio with a series of devices specifically for the field of mercury porosimetry.

The BELPORE porosimeter series consists of state-of-the-art instruments for measuring pore size distribution, pore volume, specific surface area, porosity, density and particle distribution of finely divided and porous materials.

The three mercury porosimeters from Microtrac MRB cover different pore ranges:

• BELPORE LP (1,000 – 3.25 µm)
  Degassing, Hg filling, low-pressure porosimetry
• BELPORE MP (15 – 0.0065 µm)
• BELPORE HP (15 – 0.0036 µm)
  MP & HP: High-pressure porosimetry

CONTROL & EVALUATION SOFTWARE
Mercury Porosimeter Belpore Series

The PoreInspect software for the BELPORE porosimeter series of Microtrac MRB offers a variety of functions. The software monitors and controls up to 4 measuring instruments connected via LAN completely independently with a PC and allows for individual control of all instrument parameters in real-time.

The data evaluation of the PoreInspect software not only takes the exact blank value correction into account, but also allows for a check and correction of possible sample compressibilities, guaranteeing most reliable results. Extensive evaluation options enable the selection of different pore models and their presentation as graphics and histograms. The calculations are freely selectable depending on the application and include, for example, the representation of fractal dimensions as well as calculations of tortuosity and permeability. Overlay, statistical evaluations, the creation of a method catalogue and data export are further features. The stored raw data is available at any time.
