ABSTRACT:
A method and apparatus for determining a physical property of a gas in a confined space. Gas of known volume, pressure and temperature is placed in communication with a confined space containing gas at known pressure to determine the volume of gas in the confined space using computations based on the gas laws. Alternatively, gas of known pressure, volume, and temperature may be placed in communication with a confined space containing gas at known volume to determine the pressure of gas in the confined space prior to communication with the gas of known properties. Gas volume determinations are useful, for example, to perform rheological characterizations of liquid samples.
