Description
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.
Principles of Operation
The Gas Pycnometer uses the ideal gas law to determine the volume of a sample, given a known volume of the sample chamber and gas reservoir and a change in pressure. The volume of the sample is translated into the absolute density, as the weight of the sample is known.
Applications
PMI's Gas Pycnometer is ideal for both quality control and R&D. Applications for the Gas Pycnometer span many industries ranging from automotive to nonwovens to pharmaceuticals. Specific uses include the measurement of absolute density of casting materials and ceramic components in the automotive industry, density of electrode components in the battery industry, and void volume analysis in the pharmaceutical industry.
Applicable industries include:
