At 0.01 Torr, about one-half of the ions will undergo collision, and at 0.1 Torr, essentially all of them will do so. In fact, above 0.1 Torr, many can undergo several collis

Ion-Molecule Reactions by Photoionization Techniques,e and no pyrolysis and are unaffected by electric or magnetic fields. Thus conditions in the ionization region are better controlled than is the case with electron-impact sources. The purpose of this chapter is to describe the photoionization technique with its advantages and disadvantages, to show

Chemical Ionization Mass Spectrometry, with a given compound constitute the chemical ionization mass spectrum of the compound. The number of ion types in a set of reactant ions is generally small. Because the same reactant ions react with variety of different compounds, the chemical ionization mass spectra produced from the different co

Introduction,om collisions between ions and neutral species. An ion at . = 3 was observed by Dempster. in 1916 and was correctly identified as H... By 1925, the reaction leading to its formation was well established as .. In addition, the HeH. ion had been observed in mixtures of hydrogen and helium.. In 1928, H
