Collision cross section measurements for biomolecules within a high-resolution FT-ICR cell: theory.
In this study, an energetic hard-sphere ion-neutral collision model was proposed to bridge-link ion collision cross section (CCS) with the image current collected from a high-resolution Fourier transform ion cyclotron resonance (FT-ICR) cell. By investigating the nonlinear effects induced by high-order electric fields and image charge forces, the energetic hard-sphere collision model was valida...
متن کامل4 Near - Infrared Spectroscopy
Near infrared spectroscopy (NIRS) is an imaging technique used in both clinical and emergency medicine, as well as in research laboratories to quantify and measure the oxygenation status of human tissue non-invasively. This is done by monitoring in vivo changes of the oxygen saturation of hemoglobin molecules in the body, based on the absorbance of near-infrared light by hemoglobin. With regard...
متن کاملInterrogation of N-Linked oligosaccharides using infrared multiphoton dissociation in FT-ICR mass spectrometry.
The structural elucidation of oligosaccharides remains a major challenge. Mass spectrometry provides a rapid and convenient method for structural elucidation based on tandem mass spectrometry. Ions commonly are selected and subjected to collision-induced dissociation (CID) to obtain structural information. Unfortunately, N-linked oligosaccharides are relatively large compounds and are not readi...
متن کاملOversampling Selective Accumulation Trapped Ion Mobility Spectrometry Coupled to FT-ICR MS: Fundamentals and Applications.
In the present paper, we describe the fundamentals and analytical advantages of Oversampling Selective Accumulation Trapped Ion Mobility Spectrometry (OSA-TIMS) when coupled to ultrahigh resolution mass analyzers (e.g., FT-ICR MS). During TIMS analysis, ion packages are spatially resolved based on their mobilities along the TIMS analyzer axis and multiple strategies can be utilized during the t...
متن کاملImplementation of a sensitive, narrow-band Fourier-Transform Ion-Cyclotron-Resonance (FT-ICR) detection for short-lived radionuclides at SHIPTRAP*
A very promising way towards establishing an accurate description of the inner structure of an atomic nucleus is the study of exotic nuclei. In the last few years a number of mass spectrometers based on Penning traps have been setup at rare isotopes facilities [1]. For instance SHIPTRAP at GSI is designed to provide clean and cooled beams of singly charged radioactive ions produced in a fusion-...
