HEP-E Educational Helium porosimeter


The Helium gas expansion porosimeter enables the determination of a sample’s (1” or 1.5” diameter) grain and pore volume via an isothermal helium expansion and the application of Boyle’s law and Charles’ law. Subsequently, porosity and grain density can be calculated. A provided excel template facilitates the computation of these parameters as well as calibration.
