Vinci Technologies Helium Porosimeter (HEP)
The helium gas expansion porosimeter is based on the
Boyle’s and Charles’ law expansion of helium gas and is used for direct
grain volume and pore volume measurement in auxiliary cell at isothermal
conditions. Subsequently, porosity and grain density can be derived from the
direct measurements. A data acquisition computer allows for data logging and
calculation of parameters and also calibration data. The instrument measures
grain volume of plug samples of
