Mercury intrusion porosimeter
Supervisor: Andreana Piancastelli
The mercury intrusion porosimeter is an instrument that allows the determination of the pore size distribution of solid samples. The measurement principle is based on the mercury intrusion by controlled pressurization and its detection with a capacitive system.
Thermofinnigan Pascal 140
Pascal 140 is a low pressure porosimetric station for the determination of macropores and ultra-macropores. The pore radius measurement range is between 1.9 to 58 µm (up to 900 µm with the option for ultra-macropores) and the pressure range at which the measurement takes place is between 0.01 to 400 kPa (4 bar). The pressurization takes place through the PASCAL (Pressurization by Automatic Speed-up and Continuos Adjustment Logic) system with variable speed according to the pore size and the real penetration speed of the mercury.
Thermofinnigan Pascal 240
Pascal 240 constitutes the porosimetric station that operates up to a maximum pressure of 200 MPa for the detection fo the macro and mesoporosity.
The pore radius measurement range is from 7.5 to 0.0037 microns.
The pressure range at which the measurement takes place is between 0.1 to 200 MPa (2000 bar).
