Introduction

PMI's Gas Pycnometer provides the user with a reliable measure of absolute density. The Gas Pycnometer performs a fully-automated, non-destructive test that allows the user control of the number of test iterations, and thus test length and accuracy.
 
Operating Principle
PMI's Automated Gas/Helium Pycnometer is used to determine the true volume and true density of powders and bulk solids using high-precision volume measurements and density calculations. The true volume of a solid is calculated from the measured drop in pressure when a known amount of gas is allowed to expand into a chamber containing the sample. Thus, the true volume obtained by pycnometry includes any pore volume accessible to the gas. Helium is the preferred gas, because it exhibits ideal gas behavior. The Gas/helium pycnometer measures the true volume and density of solid powders such as calcinated petroleum coke.
