High-resolution mechanical spectroscopy (HRMS) is a new term introduced in 2012 [1-4] for new methods ofUntil now, the measurements of the mechanical loss angle, ϕ , in metals and alloys in forc...
which use only moderately high dilution and modest temperatures, were selected to be easily translated onto a robotic synthesis platform. Analysis of the cages by high-resolution mass spectroscopy (HRMS) confirmed that the experimental cage topologies agreed with the computational...
Untargeted metabolomics or nontargeted analysis using high resolution mass spectrometry (HRMS) is one of the most popular analysis methods for unbiased measurement of organic compounds1,2. A typical metabolomics sample analysis workflow will follow a detection, annotation, MS/MS validation, and/or stand...

In this chapter, definitions of some concepts used in the high-resolution mass spectrometry (HRMS) are provided followed by the description of the Fourier transform mass spectrometers, that is, Orbitrap-based and Fourier Transform-Ion Cyclotron Resonance (FT-ICR) instruments. A brief description of...
A simple method is presented for identifying and confirming the components, or isotopic fine structure, of mass spectra obtained at ultra-high mass resolution with a Bruker SolariX XR Fourier transform ion cyclotron resonance (FTICR) mass spectrometer at a 7 T magnetic field. A sample compound, ...
Ultra-high-performance liquid chromatography high-resolution mass spectrometry (UHPLC–HRMS) variants currently represent the best tools to tackle the challenges of complexity and lack of comprehensive coverage of the metabolome. UHPLC offers flexible and efficient separation coupled with high-sensitivity ...
Untargeted methods are typically used in the detection and discovery of small organic compounds in metabolomics research, and ultra-high-performance liquid chromatography–high-resolution mass spectrometry (UHPLC-HRMS) is one of the most commonly used platforms for untargeted metabolomics. Although they ...
