Assembly and Demonstration of the Functionality of a Field Ionization Mass Spectrometer/Mass Spectrometer (FIMS/MS) System.

摘要

The purpose of this project was to assemble and demonstrate the functioning of a mass spectrometer/mass spectrometer (MS/MS) system that could be used eventually to study collisions between electrons and positive ions. In this phase of the program, fragmentation of ions between the first and second mass spectrometers was accomplished by collisions with a neutral gas. The existing mass spectrometer equipment was used to construct the new MS/MS system. This report describes the design and construction of the MS/MS instrument and gives the results from the early instrument performance tests.
