A rarefied piezometric uptake apparatus and method for measuring gaseous uptake for large solid samples with little or no sample preparation. Past systems and methods require extensive sample preparation. The method includes providing a rarefied piezometric uptake apparatus having a dosing chamber and uptake chamber in an improved selective fluid communication. The apparatus and method improve the measurement of gaseous uptake into solid samples resulting in improved prediction of gas migration through solid samples such as geologic formations.
