Gas chromatography–high-resolution mass spectrometry (GC–HRMS) is a powerful
nontargeted screening technique that promises to accelerate the identification of …

Detailed molecular analysis of complex mixtures such as crude oil and its fractions has been
successfully covered by a number of groups during the past two decades. On the other side …

Here, we developed and validated a new gas chromatography-atmospheric pressure
photoionisation-high-resolution mass spectrometry (GC− APPI− HRMS) method combined …

Photoionization schemes for mass spectrometry, either by laser or discharge lamps, have
been widely examined and deployed. In this work, the ionization characteristics of a xenon …

Pyrolysis is a promising way to convert plastic waste into valuable resources. However, for
downstream upgrading processes, many undesirable species, such as conjugated diolefins …

A tube plasma ionization (TPI) open-air source for gas chromatography–mass spectrometry
(GC–MS) was developed. This source is based on an inverse low temperature plasma …

The construction, critical evaluation, and performance assessment of a medium-pressure (2–
13 mbar), high-temperature chemical ionization (CI) source for application in GC-MS is …

In this work, the performance of the atmospheric pressure chemical ionization (APCI) and
photoionization (APPI) was assessed to develop a new selective and sensitive gas …

Lignin is the second most abundant biopolymer in nature and is considered an important
renewable source of aromatic compounds. One of the most promising analytical methods for …

Due to several polycyclic aromatic hydrocarbons (PAHs) being highly carcinogenic and at
the same time occurring at very low environmental concentrations up to the microgram per …
