Chapter 7. Particle Beam Mass Spectrometry for the Identification of Environmental Contaminants and Agrochemicals

摘要: Publisher Summary This chapter focuses on particle beam (PB) interfaces, which have several advantages over alternative interfacing of high-performance liquid chromatography (HPLC) with mass spectrometry (MS) for the analysis less volatile compounds. The advantage lies in its simplicity design and independence ionization options. Electron impact (EI) positive negative chemical (PCI NCI), fast atom bombardment (FAB), thermal surface (TSI) are all accessible techniques PB/MS. ability to collect EI spectral data analytes introduced into MS source through PB interface is one most attractive features. spectra then available not only library matching but also structure elucidation unknowns based well-rationalized fragmentation patterns. provides new practitioners an understanding principles pitfalls current users information about recent advances technique potential application their work.
