The development of miniature ion trap mass  spectrometers has been an active area, fueled by the  promising analytical capabilities and the  convenience of fast in situ  analysis. The objective  is to miniaturize mass spectrometers in weight,  size, and power consumption while retaining the  analytical capabilities of mass spectrometry at the  same time. The book focuses on the instrumentation  of miniature ion trap mass spectrometers, including  ionization, ion transfer, mass analyzer, ion  detection and related vacuum and electronic  techniques. Two miniature mass spectrometers, a 10  kg Mini 10 with electron impact ionization source,  developed in 2005 and a 5 kg Mini 11 with multiple  ionization sources, developed in 2008, are  introduced. The technical details of key components  are discussed. Special focus is given to a glow  discharge electron impact ionization source, which  is an ideal substitute for the filament electron  source used in the electron impact ionization, and a  discontinuous atmospheric pressure interface, which  enables the implementation of atmospheric pressure  ionization sources in miniature ion trap mas  spectrometers with limited pumping capabilities.
