This review discusses advances in the field of ambient sampling/ionization mass
spectrometry (“ambient MS” for short) with a focus on mechanistic and instrumentation …

Border control for homeland security faces major challenges worldwide due to chemical
threats from national and/or international terrorism as well as organized crime. A wide range …

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 general principles and technical implementations of traditional time-of-flight ion mobility
spectrometers and analyzers with field-dependent mobilities were reviewed in our last …

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 …

Mechanistic arguments relative to matrix-assisted laser desorption/ionization (MALDI) mass
spectrometry (MS) address observations that predominately singly charged ions are …

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 …

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