Abstract
An apparatus and method for quickly drying porous materials. A sealable chamber is connected to a cold trap which is connected to a vacuum pump. A sample is placed inside the sealable chamber. The vacuum pump is turned on and air is evacuated through the cold trap to the vacuum pump. An infrared lamp may be used to heat the chamber and sample therein directly or heated air may be allowed to enter the sealable chamber. Air may be drawn directly from the sealable chamber to the vacuum pump bypassing the cold trap. Various parameters may be used to determine if the drying process is complete, including the degree of vacuum achieved in the chamber.
