Gas pycnometer

More information.

Gas pycnometry is a common analytical technique that uses a gas displacement method to measure volume accurately. Inert gases, such as helium or nitrogen, are used as the displacement medium. The sample is sealed in the instrument compartment of known volume, the appropriate inert gas is admitted, and then expanded into another precision internal volume. The pressure before and after expansion is measured and used to compute the sample volume. Dividing this volume into the sample weight gives the gas displacement density.

The AccuPyc II 1340 Series Pycnometers are fast, fully automatic pycnometers that provide high-speed, high-precision volume measurements and density calculations on a wide variety of powders, solids, and slurries having volumes from 0.01 to 350 cm3.

The instrument completes most sample analyses in less than three minutes with excellent accuracy. After analyses are started with a few keystrokes, data are collected, calculations are performed, and results displayed without further operator intervention.

Model: AccuPyc II 1340

Manufacturer: Micromeritics
