AccuPyc > II 1340 > Gas Displacement Pycnometry System size="-1">

Gas pycnometry is a common analyticaltechnique that uses a gas displacementmethod to measure volume accurately. Inertgases, such as heliumor nitrogen,are usedas the displacement medium. The sample is sealed in the instrument compartment of known volume, the appropriate inert gas is admitted, and then expanded into anotherprecision internal volume.The pressurebefore 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 Pycnometersare fast, fully automatic pycnometers...

Organic chemicals and polymers Polymerization and organic reforming processes are used to produce desired com- pounds from raw materials. Conversion and purity can be monitored by comparingmeasured density to theoretical density ofthe desired product. Blending of materials ֖ Many powderproducts are shipped and used as blends ofprimary ingredients. The accuracy andreproducibility of the blend can be monitored by comparing the measured densities to the expected density based upon the targetrecipe of primary ingredients. The highdegree of accuracy and precision of theAccuPyc helps ensure that...
