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 …

Positive ions in the direct analysis in real time (DART) ion source are commonly formed by
proton transfer. However, the DART source is similar to atmospheric pressure …

The use of atmospheric pressure ionization (API) sources has become very popular for gas
chromatography-mass spectrometry (GC-MS) determinations. GC-API-MS shows important …

Gas chromatography coupled to high-resolution time-of flight mass spectrometry (GC-HR-
TOF-MS) is a powerful analytical technique with excellent capabilities due to its high …

The potential applications of a new atmospheric pressure source for GC‐MS analysis have
been investigated in this work. A list of around 100 GC‐amenable pesticides, which includes …

The diverse components, sources, and concentration levels of pollutants in the atmosphere
