Although the coupling of GC/MS with atmospheric pressure ionization (API) has been
reported in 1970s, the interest in coupling GC with atmospheric pressure ion source was …

We provide experimental and theoretical evidence that the primary ionization process in the
dopant-assisted varieties of the atmospheric pressure ionization methods atmospheric …

In this work, the characteristics of gas flow in inlet capillaries are examined. Such inlet
capillaries are widely used as a first flow restriction stage in commercial atmospheric …

We report on the development of a novel atmospheric pressure photoionization setup and its
applicability for in situ degradation product studies of atmospherically relevant compounds …

RATIONALE The ionization mechanisms operative in negative ion atmospheric pressure
mass spectrometry are far from being properly understood. In an excess of oxygen …

We report on a novel method for atmospheric pressure ionization of compounds with
elevated electron affinity (eg, nitroaromatic compounds) or gas phase acidity (eg, phenols) …

The performance of a KrF* bench top excimer laser and a compact diode pumped UV solid
state (DPSS) Nd: YAG laser as photo-ionizing source in LC-APLI MS is compared. The …

Trace gases in the upper troposphere and the lower stratosphere (UTLS) strongly influence
our climate and even can affect tropospheric weather. Therefore a better understanding of …

In this study a thermally sampling atmospheric pressure ionization mass spectrometer is
described and characterized. The ion transfer stage offers the capability to sample cluster …

Ionization methods operating at atmospheric pressure have largely affected the
development of analytical mass spectrometry. Today, virtually every atmospheric pressure …
