Tandem mass spectrometry in quadrupole ion trap and ion cyclotron resonance mass spectrometers.
Instruments that trap ions in a magnetic and/or electric field play a very important role in the analysis of biomolecules. The two predominant instruments in the category of trapping instrument are the quadrupole ion trap mass spectrometer (QIT-MS) and the ion cyclotron resonance (ICR) MS. The latter is also commonly called Fourier transform MS (FT-MS). The QIT is an inexpensive, simple, and ru...
متن کاملLiquid Chromatography Tandem Mass/Mass Spectrometry for the Quantification of Fudosteine in Human Serum without Precolumn Derivatization
A quantitative analysis method for fudosteine in human serum by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI/MS/MS) was established, which shows high sensitivity and selectivity. The mobile phase composition was 75% 20 mM acetic acid and 25% acetonitril, which was pumped at a flow rate of 0.40 mL/min. The overall chromatographic run time was ...

متن کاملSelected Tandem Mass Spectrometry Ion
1 Selected tandem mass spectrometry (MS/MS) ion monitoring (SMIM) is the most 2 suitable scanning mode to detect known peptides in complex samples when an ion-trap 3 mass spectrometer is the instrument used for the analysis. In this mode, the MS detector 4 is programmed to perform continuous MS/MS scans on one or more selected 5 precursors, either during a selected time interval, or along the w...
متن کاملTandem mass spectrometry in physiology.
Tandem mass spectrometry coupled to liquid chromatography (LC-MS/MS) allows identification of proteins in a complex mixture without need for protein purification ("shotgun" proteomics). Recent progress in LC-MS/MS-based quantification, phosphoproteomic analysis, and targeted LC-MS/MS using multiple reaction monitoring (MRM) has made LC-MS/MS a powerful tool for the study of cell physiology.
