The AccuPyc II Series of Pycnometers (Gas pycnometer) provides high-speed, high-precision measurements for determining the true density of powders, solids, and slurries. The analyst enters the mass of the material and then with a few keystrokes the measurement is initiated, several measurements are performed, and the density of the material is displayed.
Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This non-destructive technique utilizes the gas displacement method to measure the volume of a material. Inert gases, such as helium or nitrogen, are commonly used as the displacement medium for gas pycnometry. Density determinations from the gas displacement method are more accurate, reproducible, and faster than the traditional Archimedes water displacement method.
