Fourier-transform ion cyclotron resonance (FTICR) mass spectrometry is a high-resolution technique that can be used to determine masses with high accuracy. Many applications of FTICR-MS use this mass accuracy to help determine the composition of …

Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry (MS) remains the technique of choice for the analysis of intact proteins from complex biological systems, i.e. top-down proteomics.

2021年7月7日 · Here, we provide a critical review of recent strategies for SOM characterization by FTICR MS with emphasis on SOM sample collection, preparation, analysis, and data interpretation.

Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) is a trapped ion technique that determines the cyclotron frequency of ions trapped in a Penning trap inserted in a strong magnetic field.

2019年1月1日 · Fourier transforms ion cyclotron resonance (FT-ICR) mass spectrometry method introduced by Alan Marshall and Melvin Comisarow in 1974 is based on the measurement of the frequency of ion rotation in the magnetic field—cyclotron frequency.

This review highlights our efforts to exploit accurate mass FT-ICR-MS technologies with chemical cross-linking and developments being pursued to realize parallel MS array capabilities that will further advance visualization of the interactome.

2015年2月1日 · This article reviews the development of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) in several respects: (a) a strong static magnetic field serves to convert ion mass-to-charge ratio into cyclotron frequency.

2014年2月10日 · Fourier transform ion cyclotron resonance (FT ICR) mass spectrometer offers highest resolving power and mass accuracy among all types of mass spectrometers. Its unique analytical characteristics made FT ICR important tool for proteomics, metabolomics, petroleomics, and investigation of complex mixtures.

For this we use a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS). In this technique, the mass-to-charge ratio (m/z) of an ion can be experimentally determined by measuring the frequency at which the ion processes in a magnetic field.

2004年3月12日 · With the advent of electrospray ionization (ESI), FT-ICR mass spectrometry has become a powerful tool for the investigation of biological macromolecules, such as the study of non-covalent interactions of proteins.
