Coupling of motion of the ion clouds with close m/z values is a well-established phenomenon for ion-trapping mass analyzers. In Fourier transform ion cyclotron resonance mass spectrometry it is known as ion coalescence. Recently, ion coalescence was demons ...
Recent experimental and theoretical findings suggest that the concept of time-dependent instantaneous frequency(IF) is required to comprehensively describe ion motion and mass spectra generation in Fourier transform mass spectrometry (FTMS). Here, we deriv ...
Nowadays, among the instrumentation park of mass spectrometry, Fourier transform mass spectrometers (FTMS), including ion cyclotron resonance (ICR) and Orbitrap FTMS, provide the highest analytical performance for accurate measurements and mass resolution. ...
To advance Fourier transform mass spectrometry (FTMS)-based molecular structure analysis, corresponding development of the FTMS signal processing methods and instrumentation is required. Here, we demonstrate utility of a least-squares fitting (LSF) method ...
In this chapter, we describe the advances in high-resolution and tandem mass spectrometry applied for structural analysis of complex molecular systems. Focus is made on Fourier transform mass spectrometers (FTMS) because of their ability to routinely provi ...
A self-consistent modelling of ion cyclotron resonance heating (ICRH) is reviewed with the aim of obtaining a fast robust scheme suitable for routine simulation for transport codes and data analysis. Due to the complexity of calculating the wave field and ...
The performance of the high-field Orbitrap Fourier transform mass spectrometer (FTMS) is evaluated in the context of petroleum sample analysis. Pertinent characteristics including resolving power, mass accuracy, and spectral dynamic range are tested with r ...
A multielectrode ion cyclotron resonance (ICR) cell, herein referred to as the 4X cell, for signal detection at the quadruple frequency multiple was implemented and characterized on a commercial 10 T Fourier transform ICR mass spectrometer (FT-ICR MS). Not ...
Qualitative and quantitative analyte analysis is omnipresent: from quality control in food, pharmaceutical, biotechnology industries, to new molecular syntheses, detection of explosives and drugs, as well as natural compound mixture analysis, such as crude ...
The current paradigm in ion trap (cell) design for Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) is the ion detection with wide aperture detection electrodes. Specifically, excitation and detection electrodes are typically 90A deg ...
