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.

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.

TL;DR: In this article, a dual octupole ion injection system was proposed for high performance mass analysis at low pressure, which was demonstrated on a mixture of 500 fmol of each of three peptides.

TL;DR: The principles and techniques of the highest-resolution analytical mass spectrometers (time-of-flight and Fourier transform ion cyclotron resonance and orbitrap mass analyzers) are reviewed and some representative high-resolution applications are described.

TL;DR: In this article, a high-field (9.4 T) Fourier transform ion cyclotron resonance mass spectrometer coupled to an external micro-electrospray ion source was used to identify 12 major heteroa...
