Ambient ionization is a set of mass spectrometric ionization techniques performed under
ambient conditions that allows the direct analysis of sample surfaces with little or no sample …

The applications of organic matrices for matrix assisted laser desorption/ionization mass
spectrometry (MALDI-MS) are reviewed. Recent advances of MALDI-MS using organic …

In this review we highlight the general change in perception in the field of ambient mass
spectrometry that it is the immediacy of sample preparation that differentiates the ambient …

The definition of ambient ionization is updated from “no sample preparation” to sample
preparation proximal and in real time with the ionization and analysis step. We differentiate …

A new inlet ionization method requiring no voltage or laser, and using water, methanol, or
water/organic solvent mixtures, is shown to produce mass spectra similar to those obtained …

The systematic study of the temperature and pressure dependence of matrix-assisted
ionization (MAI) led us to the discovery of the seemingly impossible, initially explained by …

An astonishingly simple new method to produce gas-phase ions of small molecules as well
as proteins from the solid state under cold vacuum conditions is described. This matrix …

An extra dimension of polymer analysis: ion mobility spectrometry-mass spectrometry (IMS-
MS) separates ions according to their size in the gas phase, allowing differentiation of linear …

The introduction of electrospray ionization (ESI) and matrix-assisted laser
desorption/ionization (MALDI) for the mass spectrometric analysis of peptides and proteins …

Matrix assisted inlet ionization (MAII) is a method in which a matrix: analyte mixture
produces mass spectra nearly identical to electrospray ionization without the application of a …
