In addition, the eight glycated sites of R-Oval were identified by the HCD MS/MS, which are located in the hydrophilic region and their adjacent amino acids are hydrophilic amino acids, acidic amino acids or basic amino acids. Orbitrap-based mass spectrometers are used in proteomics and are also used in life science mass spectrometry such as metabolism, metabolomics, environmental, food and safety analysis. Most of them are interfaced to liquid chromatography separations, [11] though they are also used with gas chromatography [13] and ambient ionization methods.

Currently, glycans are attracting attention from the scientific community as potential biomarkers or as post-translational modifications … LC-MS/MS Spectrum - LC-ESI-ITFT (LTQ Orbitrap XL, Thermo Scientfic) , Positive: Splash Key: splash10-03di-1900000000-53373dc0755caa954310 View in MoNA : Spectrum View.

Dmitry Shevela. Isotope-ratio The Orbitrap is an ion trap mass analyzer that consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector. Ions entering the Orbitrap are captured through "electrodynamic squeezing," after which they oscillate around the central electrode and in between the two outer electrodes. The Orbitrap is an ion trap mass analyzer that consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector.
