ABSTRACT:
A method for measuring the volume of a sample comprises measuring the weight of the sample by means of a balance within a sealed vessel containing a first gas; then replacing the first gas in the vessel with a second gas having a density different from that of the first gas; and then measuring the weight of the sample by means of the balance within the sealed vessel containing the second gas to determine a change of weight of the sample corresponding to the change of the gas in the sealed vessel. Then the volume of the sample is calculated according to Archimedis' principle as a function of the value of the difference between the density of the first gas and the second gas, and the value of the change of weight of the sample corresponding to the change of the gas. An apparatus for measuring the volume of the sample is also disclosed.
