p]), measured by pycnometry on the pulverized material, the percentage porosity was calculated with the following equation:
True density of Neusilin US2 and S-SNEDDS was measured using Helium Pycnometry (Smart Pycno 30, Smart Instruments, Mumbai).
1 Helium Pycnometry for Particle Density Measurements
Helium pycnometry and mercury porosimetry techniques were used to obtain the internal porosity of the coatings that, together with the average pore size, are key parameters for characterizing the mass transport through paint films.
Density data were collected from the diamond core utilising the water immersion method and pycnometry methods.

Gas pycnometry is a physical testing method that uses gas displacement to determine the volume and density of a nonvolatile solid sample.
These services include: particle size (sedimentation, electrozone sensing, OptiSizer PSDA optical imaging, or high definition laser particle size), surface area, pore size and size distributions, pore volume, density and volume by gas pycnometry or mercury porosimetry, envelope volume and density by a patented dry-fluid technique, T.
Since subsequent porosity calculations required the bulk CoCr density, pycnometry measurements were performed on CoCr powder that was nominally identical to that used in the production of these disks.
The question on open versus closed cell structure could in principle be determined by helium pycnometry (17).
These include: particle size, surface area, pore size and size distributions, pore volume, density and volume by gas pycnometry or mercury porosimetry, envelope volume and density by a patented dry-fluid technique, and T.
