Highly Adaptable Density Determinations The AccuPyc II 1340 Gas Displacement Pycnometry System

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 that provide high-speed, high-precision volume measurements and density calculations on awide variety of powders, solids, and slurrieshaving volumes from 0.01 to 350 cm

Wide Variety ofStandardFeatures

•Simple calibration process allows theuser to determine easily the volume ofthe instrument sample cell and expansionchambers using a traceable standard volume. After calibration, the cell and expansion chamber volumes are stored automatically.•A unique run precision feature increasesthe precision of analysis results byreporting data from five consecutive measurements that are within a user- specified tolerance. This feature allows early termination of analysis, therebydecreasing the number of cycles neededfor accurate results.•Sample mass may be directly input from an analytical weighing through an RS-232 port.•USB ports on the rear panel of the controlmodule allow for connection to a printer (output of analysis and calibration results) and keyboard (alphanumericcharacter input). The USB port is alsoused for installing software upgrades.•An Ethernet port on the rear panel of thecontrol module enables the user to e-mail reports, send data to a web browser forarchiving, or interface with the AccuPycII 1340 Windows
