Fourier Transform Ion Cyclotron Resonance (FT-ICR) is an advanced mass spectrometry technique that allows for the precise measurement of the mass-to-charge ratio of ions by utilizing a strong magnetic field and Fourier transform analysis. This method is known for its high resolution and sensitivity, making it a crucial tool in the study of complex mixtures, such as those encountered in metabolomics. FT-ICR provides detailed insights into molecular structures, enabling researchers to understand metabolic pathways and the roles of various metabolites.
