In this talk, Robert B. (Chip) Cody, Ph.D, Principal Scientist at JEOL USA, Inc., will describe how integrated soft ionization methods, such as field ionization and field desorption (FI/FD) or photoionization (PI), can complement traditional electron ionization (EI) and chemical ionization (CI) to provide critical molecular weight information, thereby simplifying the characterization of complex mixtures and eliminating interferences in biomarker analysis.
The combination of high-resolution accurate mass spectra with enhanced separation methods, such as comprehensive two-dimensional gas chromatography (GCxGC), and advanced data analysis provides powerful tools for characterizing complex mixtures. Even without chromatographic separation, field ionization and field desorption can provide critical information about the sample. Examples will be presented for the characterization of crude oil and diesel, biomarker analysis, fresh and used mechanical pump oils, and pyrolysis oils.
