Fourier Transform Mass Spectrometry for Analysis of Organic Mixtures

Source

Applications of Fourier Transform Mass Spectrometry (FTMS) as a high performance mass spectrometer are presented. Gas chromatography (GC/FTMS analysis of an unleaded gasoline provides, in addition to electron ionization spectra for mass spectral library search algorithms, low ppm error accurate mass measurement capabilities that deliver real time elemental analysis of each eluting component. Suspended trapping pulse sequences are also examined as a means to extend dynamic range in the trapped ion cell and lower detection limits. Laser desorption/ionization (LD/I) is examined as an alternative to LC/MS for extracting structural information from non-volatile or thermally labile organic materials in mixtures. A prominent ion representative of a component molecular weight is usually generated in LDI mass spectra which facilitates mixture analysis without prior separation.
