Notes:
We describe an apparatus for measuring high-resolution, low-noise vapor-pressure isotherms of physisorbed films. The data can be numerically differentiated to yield precise values of the two-dimensional isothermal compressibility of monolayer films, allowing detailed analysis of phase transitions. The apparatus is a carefully implemented, automated adaptation of standard volumetric systems.
