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

β¦ Synopsis
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry is employed to detect the presence of the bacteriological sex factor, a trait that allows some bacteria to transfer genetic information to others by means of conjugation. The principal advantage of the method is its speed. Twenty different strains of E. coli were analyzed and the results were consistent with previously known genetic information. The sex factor could be transferred from one strain to another and the outcome verified by mass spectrometry.

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
