Gas pycnometers

Density Determination Made Simple – Fast, Accurate, and Reliable Gas Pycnometry

Gas pycnometry is a fast, precise, and cost-effective technique for measuring the volume of powders, solid, and liquid materials, enabling reproducible and accurate density determinations. By measuring the volume of gas displaced by a sample, a pycnometer provides insight into material properties such as purity and sample differentiation.

Now available through Malvern Panalytical, Micromeritics’ industry-leading gas pycnometer, the AccuPyc, delivers advanced automation and reliability for a wide variety of applications.

Industry applications

Gas pycnometers are essential instruments for accurately measuring the volume and density of powdered materials, formed solids, liquids and slurries. These measurements are vital in various industries for quality control, material characterization, and performance evaluation. Key applications include:
In the pharmaceutical industry, gas pycnometry is used to determine the skeletal density of powders, helping optimize formulations and processes, control composition, ensure uniformity, and improve flow properties.
The density of battery cathode and anode materials is directly related to their porosity, impacting energy storage capacity per unit volume. It also serves as a key indicator of material purity and composition, both essential for enhancing battery performance and capacity.
The density of catalysts is a crucial parameter for evaluating the composition of supports and finished products, including crystallinity, porosity, and formulation.
Gas pycnometry is widely used to analyze the density of ceramics, composites, polymers, gels and other advanced materials.
