Paper Abstract

A miniature quartz crystal microbalance (mQCM), called the MK 16 QCM Sensor by QCM Research, is fully described in terms of its temperature range (5°K to 360°K), its ability to raise the temperature of the crystals independently of the case (which is held at --.10°K) with zero to 1.5 watts of power, and be designed as a flight qualified unit. As a QCM sensor, the MK 16 not only measures the mass of contaminates that arrive with time (6.7 Hz per monolayer) but also by raising the temperature of the crystal, constituent gasses will be re-emitted from the crystal which can be further analyzed by QCM thermogravimetry (QTGA).
