Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Exploring Unspecific Peroxygenase Selectivity with Diverse Hydrocarbon Substrates

ChemistryOpen, EarlyView.
Unspecific peroxygenases (UPOs) are versatile enzymes that can be used for different reactions. However, selectivity of UPOs needs to be evaluated for the desired application. Thus, the selectivity of a panel of UPOs was evaluated in this work, and it revealed diverse reactivity profiles depending on the enzyme and substrate.
