This facility is charged with developing and exploiting the unique capabilities of Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry, and leads the world in instrument and technique development as well as novel applications of FT-ICR mass spectrometry.

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 · Fourier transform ion cyclotron resonance mass spectrometry represents an increasingly powerful tool for the study of biological molecules, especially within “proteomics.” 93–95 Improvements in FT-ICR analyzer cell design, increases in magnetic field strength, addition of new features such as types of tandem mass spectrometry experiment ...

2022年6月18日 · The advance of Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) makes the detailed characterization of DOM at the molecular level possible.

FT-ICR MS has higher mass resolution and accuracy than any other MS system and can detect multiple mass-to-charge ratio ions simultaneously. However, FT-ICR MS can be prohibitively expensive at $1-2 million for a standard instrument.

The EU FT-ICR MS network includes 10 FT-ICR MS centers from 8 different European countries (Belgium, Czech Republic, Finland, France, Germany, Italy, Portugal, and United Kingdom) and 1 third country (Russia), a European FT-ICR MS manufacturer and 2 SMEs.

Here, we present an introduction to the principles and generic appli-cations of FT-ICR MS, at the minimum depth needed to explain the concepts, directed to those without prior experience in the field.

2014年3月28日 · FT-ICR MS achieves the highest resolution and best mass measurement accuracy of any mass spectrometry method. These remarkable achievements are due to several factors, including multi-channel detection, measurement of frequency, magnetic field stability, and dependence of cyclotron frequency on only the magnetic field and ion mass to charge ...
