Journal ArticleDOI
Fourier transform ion cyclotron resonance mass spectrometry: A primer
TL;DR: This review offers an introduction to the principles and generic applications of FT-ICR mass spectrometry, directed to readers with no prior experience with the technique, and lists accurate fundamental constants needed for ultrahigh-precision analysis.
Journal ArticleDOI
Fourier Transform Ion Cyclotron Resonance Spectroscopy
TL;DR: The Fourier transform ion cyclotron resonance (FT-ICR) 1.5 mass spectrometer as discussed by the authors was developed for mass spectroscopy and it can be used to obtain the whole spectrum in a very short period of time.
Journal ArticleDOI
Kendrick mass defect spectrum: a compact visual analysis for ultrahigh-resolution broadband mass spectra.
Christine A. Hughey,Christopher L. Hendrickson,and Ryan P. Rodgers,Alan G. Marshall,Kuangnan Qian +4 more
TL;DR: It is possible to break a broadband mass spectrum into 1-Da segments, rotate each segment by 90 degrees, scale each segment according to its mass defect, and compress the spacing between the segments to yield a compact display, illustrated for experimental electrospray ionization FTICR ultrahigh-resolution mass spectra of a petroleum crude oil.
Journal ArticleDOI
Petroleomics: The Next Grand Challenge for Chemical Analysis
Alan G. Marshall,Ryan P. Rodgers +1 more
TL;DR: The key features that have opened up this new field have been ultrahigh-resolution FT-ICR mass analysis, specifically, the capability to resolve species differing in elemental composition by C(3) vs SH(4) (i.e., 0.0034 Da), thereby extending to >900 Da the upper limit for unique assignment of elemental composition based on accurate mass measurement.
