The ionization of nucleosides in matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was systematically investigated using adenine (A), thymine (T), guanine (G) and cytosine (C) with several common matrices. Experimental results of the protonation and deprotonation of the ba

Oligonucleotide sequencing by fragmentation in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry has been demonstrated. With this sequencing method, the preparation of oligonucleotide ladder products and gel electrophoresis are not required, thus the sequencing
This study presents matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) as a powerful tool to analyze and characterize oligonucleotides covalently linked to a solid support during their synthesis. The analysis of the fragment ions generated either in negative o
The limits of performance of a linear time-of-flight mass spectrometer using matrix-assisted laser desorp tionlionization have been tested. Effects of the pressure in the vacuum system and the sampling rate of the digital oscilloscopes on mass resolution have been investigated. Spectra recorded at d
The time-of-flight effect in Fourier transform mass spectrometry (FTMS) with an external ion source was quantified. The time-of-flight profiles of ions of different masses were measured by stepping the time interval between the ionization pulse and the gating of the trapping voltage (T gate ). The o
