Abstract : A combination drift tube and quadrupole mass spectrometer was used to make measurements of the rate coefficients for the hydration of thermal energy atmospheric negative ions at low partial pressures of water vapor in oxygen at 300K. The partial pressure of the water was determined from measurements of the rate of production of positive ions produced by electron ionization of the gas effusing from the orifice between the drift tube and the mass spectrometer.
