Heat quantity measurement device during simultaneous measurement of evaporation/condensation kinetics in minute liquid amounts, has a component for determining thermodynamic parameters.

摘要

An upper part (251) forming a hollow cylinder is made air-tight in a measuring chamber (25) by a base (252) for controlling a rod-shaped holder (261) for a first weighing scale (262) in an ultra micro balance (26), directly on which or via a carrier (263) there is a cup/second scale (264) with a sample liquid (265). This cup is thermally insulated from its base. A measuring device determines changes dependent on time in the smallest amounts of liquid. The measuring chamber has a computer to register, display, evaluate and/or subsequently process measurement values.
