摘要：

This article describes an improved version of the graphite fiber microbalance, a device that was recently proved to be a useful tool for investigating adsorption phenomena. Hydrodynamic effects, that may yield large errors in the calculation of the adsorbed mass, if not properly evaluated, are carefully accounted for. An accurate measurement of the film coverage is obtained by using a correction to Stokes equations in the region of semiballistic regime that is much simpler than the slip theory used by other authors.
