TQCM Monitored Bakeout

The use of Thermoelectric Quartz Crystal Microbalances (TQCM) is highly recommended by the European Space Agency (ESA) to demonstrate the effectiveness of a Vacuum Thermal Bakeout. We have two vacuum facilities that provide state-of-the-art outgassing monitoring using a trio of TQCMs.

A TQCM is a device used to monitor in real-time the evolution of the amount of volatile condensable materials emitted from a device/unit under test. This is achieved by measuring the mass flow of contaminants that condense at a specific temperature on its sensing surface.
