Gas Pycnometry Volume and Density
Simply defined as mass divided by volume (g/cm3), density measurements guide the formulation process and influence the overall quality of manufactured products. Micromeritics gas pycnometers are being used worldwide to obtain high-speed, high-precision volume measurements and density calculations on a wide variety of powders, solids, and slurries. These measurements are necessary in the manufacture of many of today’s products.
Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This technique is non-destructive as it uses the gas displacement method to measure volume. Inert gases, such as helium or nitrogen, are used as the displacement medium. Density calculations using the gas displacement method are much more accurate and reproducible than the traditional Archimedes water displacement method.
