BPDA2d - a 2D global optimization-based Bayesian peptide detection algorithm for liquid chromatograph-mass spectrometry
MOTIVATION Peptide detection is a crucial step in mass spectrometry (MS) based proteomics. Most existing algorithms are based upon greedy isotope template matching and thus may be prone to error propagation and ineffective to detect overlapping peptides. In addition, existing algorithms usually work at different charge states separately, isolating useful information that can be drawn from other...
متن کاملLiquid Chromatography - Mass Spectrometry
In this article, selected examples of applications of liquid chromatography coupled to mass spectrometry are given. The examples include the analysis of i) impurities in manufactured, pharmaceutical or synthesis products, ii) polyphenols in natural products, and iii) phytohormones in plant extracts. Finally, examples of applications of molecular characterization via flow injection analysis by e...
متن کاملLiquid Secondary Ion Mass Spectrometry
Liquid secondary-ion mass spectrometry (liquid SIMS) is an obsolescent ionization technique that revolutionized the analyses of large biological molecules in the 1980s. The term includes fast atom bombardment mass spectrometry (FAB-MS). The technique has been largely superseded by electrospray ionization. This account will cover the history of the technique, the principles of the operation, and...
متن کاملDetermination of Chloramphenicol in Fish Meat by Liquid Chromatograph-Atmospheric Pressure Photo Ionization-Mass Spectrometry (LC-APPI-MS) Application
A liquid chromatography-atmospheric pressure photoionization-mass spectrometry method was developed for the determination of chloramphenicol antibiotics in fish meats. For the optimization of APPI, several ion source parameters were examined. Using the optimized parameters, simple mass spectra and a strong signal corresponding to [M-H] was observed. The samples were extracted with ethylacetate ...
متن کاملLiquid chromatography-inductively coupled plasma mass spectrometry.
The technique of coupling liquid chromatography to inductively plasma mass spectrometry (ICP-MS) is reviewed. A brief introduction to the ICP-MS instrument is given as well as methods to couple the two analytical instruments together. The various types of LC that have been used with ICP-MS detection are discussed and advantages over traditional methods of detection are highlighted, such as the ...
