Title: Soft ionization mass spectral methods for lipid analysis
Abstract: Chemical ionization (CI), field ionization (FI) and field desorption (FD) are sometimes preferable to electron impact (EI) mass spectrometry as methods for obtaining abundant high-mass ions from lipids. FD often provides mass spectral information which is unobtainable by other methods, and is the best method for obtaining molecular weight information. Fragment ions are observed in the spectra from all the ionization methods, which provide structural information complementing that obtainable from an EI spectrum. Using CI, high-mass ions carrying a large proportion of the total ionization current can be monitored by selected ion monitoring, resulting in enhanced sensitivity for quantitative studies in some cases.
