Abstract : Ten mass spectra from each of twelve compounds including methane, n-butane, 2-butyne, 1-butene, iso-butene, diethyl ether, benzene, ethanol, iso-pentane, ethyl iodide, toluene and ethyl acetate were obtained using the Bendix time of flight mass spectrometer. The spectra from each compound were obtained at 15, 17, 20, 25, 30, 35, 40, 50, 70 and 100 volts electron bombarding energy. Representative ionization efficiency curves are plotted from each compound. Other spectra are discussed and recommendations made for electron bombarding energies to be used in analytic spectroscopy with the Bendix time of flight instrument. (Author)
