Abstract :
Several quartz crystal microbalance (QCM) sensing techniques have been applied for the selective detection of volatile organic solvents in the pre-explosive vapour concentration range. Through the use of sensor arrays and QCM dissipation measurements, reliable detection and discrimination is made possible.
