Abstract
Molybdenum oxide is doped with vanadium, nobidium, tantalum or titanium to form a stable MOtheta phase crystal structure as a vapor sensitive material for detecting vapors of volatile organic compounds. That material is used between electrodes connected to a measuring device to measure a change in an electrical quality in the presence of a vapor of a volatile organic compound. Concentration of the vapor is measured to low part per million ranges.
