Abstract

Quartz crystal oscillators can be sensitized to selectively respond to the presence of solvent vapors by overcoating the crystals with a thin film of a sensitizing base mate~ rial such as a light oil0 In the presence of a solvent vapor the oscillator responds with a frequency deviation in positive correlation to the vapor concentration of the solvent0
