Mass Spectra Correlations And The Appearance Potentials Of The Major Tobacco Alkaloids, William Frederick Kuhn

Master's Theses

The main objectives of this investigation were three­ fold: (1) to design and fabricate a heated inlet system for the mass spectrometer; (2) to obtain the mass spectra of the major tobacco alkaloids under normal operating conditions; and ( 3) to determine the ionization potentials of the alkaloids as well as the appearance potentials of some of the major fragment ions derived from the alkaloids.

The mass spectrometer is designed to analyze only materials in the vapor state . Since some materials do not exert sufficient vapor pressure at room temperature under reduced pressure to be analyzed directly, it is …
