Effective Volumetric Factor for Inhomogeneous Temperature in Volumetric Measurements of Gas Absorption and Desorption

Accounting of effective volumetric factor for the measurement at inhomogeneous temperature allows to the simplify the measurement process avoiding a pre-calibration with a noble gas. The volumetric correction in form of the volumetric factor is calculated analytically by modeling of the temperature profile in the volumetric apparatus, and provides a quite agreement with the measured results. The calculation can be applied for each volumetric measurement with an inhomogeneous temperature distribution
