Service Description


Density is defined as the ratio of weight to volume. Grain volume can be measured by the Boyle's law method. To measure grain volume, the sample is placed into a chamber of known volume. Helium, from a reference cell at known pressure, is then expanded into the sample chamber. The equilibrium pressure of the system is monitored and Boyle's Law is used to calculate the grain volume. Grain weight also can measure by direct measurement.
