Helium Density Pycnometer - Gas Pycnometer Analyzer
- Product Code: G-DenPyc 2900
Introduction
A gas pycnometer operates by detecting the pressure change
resulting from displacement of gas by a solid object. Expanding a quantity of
gas at known pressure into an empty chamber and measuring the pressure
establishes a baseline.Then a sample is placed in the chamber and the chamber
is resealed. The same quantity of gas at the same pressure is again expanded
into the sample chamber, and the pressure is measured. The difference in the
two pressure combined with the known volume of the empty sample chamber allows
the volume of the sample to be determined by way of the gas law.
The accuracy and precision of the gas pycnometer in determining
density is good, but the method relies greatly on the cleanliness of the sample
material and purity of the analysis gas. In this case, TESTFORM had
explored a smart sample preparation degasser for materials handle, can
guarantee to gain the "cleanliness" testing data.
