Apparatus for Adjusting and Maintaining Humidity of a Gas at a Constant Value within a Closed System

摘要

An improved apparatus was developed for maintaining the humidity of a gas at a constant value within a closed system for long periods of time by using saturated salt solutions and isolating the sample environment from the salt environment. This apparatus avoids many problems associated with humidity/temperature chambers and off-the-shelf laboratory equipment, such as desiccators, that are being used for environmental studies under controlled conditions of humidity and temperature. 3 refs., 2 figs.
