Gas Displacement Pycnometry System




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.

  • Maintain product integrity with this non-destructive test
  • Eliminate error with programmable automatic repeat and data acquisition set to your tolerances to comply with your SOPs
  • Ability to use a variety of gases
  • Maximize your investment-Adaptive configuration to meet your sample size needs
  • Low-cost, minimal maintenance, and small footprint
  • Increase efficiency and compliance with barcoding compatibility
  • Speed of analysis, accuracy, repeatability, and reproducibility
  • Versatility of keypad or Windows software operation
  • Eliminate procedural steps with direct input from an analytical balance

This technique uses the 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 pressures observed upon filling
the sample chamber and then discharging it into a second empty chamber allow computation of the sample solid phase volume. Helium molecules rapidly fill pores as small as one angstrom in diameter; only the solid phase of the sample displaces the gas. Dividing this volume into the sample weight gives the gas displacement density.
