Working Principle

The G-DenPyc 2900 uses gas expansion and volume displacement to determine the true density of solid and powder samples.

1. Sample loading: A known quantity of sample is placed in the measurement chamber.

2. Gas introduction: A selected test gas, such as helium or nitrogen, is introduced into the chamber under controlled pressure conditions.

3. Gas expansion: The gas expands between calibrated volumes, and the instrument measures the resulting pressure changes.

4. Volume calculation: Using gas behavior, calibrated chamber volumes, and pressure measurements, the system calculates the volume occupied by the solid material.

5. Density determination: The true density is calculated from the sample mass and measured solid volume.

6. Result processing: The integrated software processes the measurements and displays the results automatically.

For suitable rigid foam samples, gas-accessible pore volume measurements can also support the evaluation of open-cell and closed-cell characteristics, depending on the configured test method.
