AbstractThe ion-to-neutral ratios of four commonly used solid matrices, α-cyano-4-hydroxycinnamic acid (CHCA), 2,5-dihydroxybenzoic acid (2,5-DHB), sinapinic acid (SA), and ferulic acid (FA) in matrix-assisted laser desorption/ionization (MALDI) at 355 nm are reported. Ions are measured using a time-of-flight mass spectrometer combined with a time-sliced ion imaging detector. Neutrals are measured using a rotatable quadrupole mass spectrometer. The ion-to-neutral ratios of CHCA are three orders… Expand
Temperature Dependence of Desorbed Ions and Neutrals and Ionization Mechanism of Matrix-Assisted Laser Desorption/Ionization.
TLDR
The results closely agreed with the predictions of the temperature-dependent ion-to-neutral ratio using the thermal model, indicating that thermally induced proton transfer is the dominant reaction that generates initial ions of 2,5-DHB in UV-MALDI. Expand
Ionization Mechanism of Matrix-Assisted Laser Desorption/Ionization.
TLDR
It is demonstrated how none of the arguments raised to challenge thermal ionization are valid before concluding that thermal proton transfer must play a crucial role in the ionization process of MALDI. Expand
Toward understanding the ionization mechanism of matrix-assisted ionization using mass spectrometry experiment and theory.
TLDR
3-NBN produces intact, highly charged ions of nonvolatile compounds in high-vacuum TOF mass spectrometers with the aid of ablation and/or heating by laser irradiation, and shows a different ionization mechanism from that of typical MALDI matrices. Expand
Laser Pulse Width Dependence and Ionization Mechanism of Matrix-Assisted Laser Desorption/Ionization
TLDR
A comparison of the experimental measurements and numerical simulations showed that the predictions of thermally induced proton transfer model were in agreement with the experimental data, but those of the multiphoton ionization model were not. Expand
Oxidative radical driven cleavage of peptide backbone caused by matrix-assisted laser desorption/ionization-in-source decay with low matrix-to-peptide molar ratios
Abstract The influence of matrix-to-analyte molar ratio (M/A) on the formation of in-source decay (ISD) fragment ions was examined by matrix-assisted laser desorption/ionization (MALDI) of peptidesExpand
Generation of gas-phase ions from charged clusters: an important ionization step causing suppression of matrix and analyte ions in matrix-assisted laser desorption/ionization mass spectrometry.
TLDR
Evidence is presented suggesting that the generation of gas-phase ions from charged matrix/analyte clusters may induce significant suppression of matrix and analyte ions in MALDI-MS. Expand
Detection of Neutral Species in the MALDI Plume Using Femtosecond Laser Ionization: Quantitative Analysis of MALDI-MS Signals Based on a Semiequilibrium Proton Transfer Model.
TLDR
Numerical simulation based on this semiequilibrium model successfully reproduced variations of MALDI signal intensities AH+ and MH+ with two parameters: the fraction of ionized matrix a ≤ 10-5 and an effective temperature T = 1200 and 1100 K for Phe/D HB and Ala/DHB systems, respectively. Expand
New Strategy to Preserve Phosphate by Ionic Liquid Matrices in Matrix-Assisted Laser Desorption/Ionization: A Case of Adenosine Nucleotides
TLDR
It is demonstrated for the first time that 2,5-dihydroxybenzoic acid pyridine (DHBP) is one of the most effective matrices for further quantitative analysis of adenosine nucleotides and enhances the fundamental understanding of MALDI. Expand

TLDR
The CPCD model of matrix assisted laser desorption ionization is restricted to relative rather than absolute yield comparisons because the rate constant for one step in the model was not accurately known, leading to good agreement with experimental yield versus fluence data for 2,5-dihydroxybenzoic acid. Expand
Competing Deprotonation and Electron Capture Dissociation in MALDI Mass Spectrometry.
TLDR
It is shown herein that negative ions can be generated in different ways and it is proposed that negative charges of deprotonated ions prevent electron transfer due to the repulsive force. Expand
