摘要：

A high precision, computer-controlled adsorption isotherm apparatus has been constructed and used to investigate a variety of physisorbed systems. Suitable for absolute measurements, this apparatus features good vapor pressure resolution and outstanding temperature stability. The hallmark of the apparatus, however, is the graphical computer interface, written using the popular LABVIEW package, which offers a flexibility and ease-of-use not achieved in previous automated systems. This article will demonstrate the quality of data obtainable with this system, as well as the simplicity of operation afforded by the graphical interface. (C) 1996 American Institute of Physics.
