Recent developments in atmospheric pressure photoionization (APPI), which is one of the
three most important ionization techniques in liquid chromatography‐mass spectrometry, are …

It is well documented since the early days of the development of atmospheric pressure
ionization methods, which operate in the gas phase, that cluster ions are ubiquitous. This …

Plasma-based ambient desorption/ionization sources are versatile in that they enable direct
ionization of gaseous samples as well as desorption/ionization of analytes from liquid and …

Currently used analytical techniques for halogenated aromatic environmental contaminants
such as polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls …

Rationale The ionization process is essential for successful mass spectrometric (MS)
analysis because of its influence on selectivity and sensitivity. In particular, certain solvents …

This chapter focuses on the practical application of atmospheric pressure photoionization
(APPI) and low‐pressure photoionization (LPPI) and illustrates a number of applications for …

Methoxydiphenylmethane (4-MDM), a selective augmenter of Leukotriene A 4 Hydrolase
(LTA 4 H), is a new anti-inflammatory compound for potential treatment of chronic obstructive …

Rationale As in the case with positive ion atmospheric pressure photoionization (PI‐APPI),
the addition of dopants significantly improves the sensitivity of negative ion APPI (NI‐APPI) …

We investigate for the first time the gas-phase lowest-lying valence, Rydberg and ionic
electronic states of 2, 4, 6-trichloroanisole (TCA) using synchrotron radiation for …

Ambient desorption/ionization (ADI) sources have eliminated the requirements of extensive
sample preparation and/or time-consuming chromatographic separations prior to mass …
