The Micromeritics AccuPyc 1330 helium pycnometer determines powder and solid densities. After properly preparing the sample with heat and/or vacuum, helium gas fills the sample chamber and pressure is measured. The helium then enters another empty chamber and the pressure in both chambers is measured. The sample volume is calculated based on these pressures and then with the known weight of the sample, the density is then calculated. The helium is able to fill all spaces and all but the smallest micropores open to the atmosphere.

IMPORTANCE:

Changes in vendor materials or in processing could affect the density of the product. The helium pycnometer rapidly determines the apparent density of raw materials or finished product and when compared to a known standard, will indicate changes in the product.

RESULTS:

A detailed report illustrates the volume and density of the analyzed sample.
