Accurately measure pore/grain volume of porous materials
The Grace Instrument M9145 Porosimeter is a nitrogen/helium gas instrument used to measure pore volume and grain volume
of core samples. Porosity and grain density measurements may also be obtained from the M9145 PC data acquisition software.
The core sample is placed into a coreholder or cupholder cell, usually 1 and 1.5 inches in diameter.
The cell is then seated within a reservoir of known volume and pressurized.
Once the pressure has stabilized, a valve is opened to allow in helium gas that isothermally expands.
After the pressure within the reservoir stabilizes again, the new pressure in the system is recorded and measured against the original known pressure.
The porosity and grain density of the sample may be calculated through the use of Boyle's Law (P1V1 = P2V2).
