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

Mass Spectrometry Reviews, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 6, 2024

ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient tools with various atmospheric pressure processes. In this review, we summarize a historical overview of the development DBDI, highlighting key principles gas‐phase ion chemistry mechanisms underlying processes within DBDI source. These start formation reagent ions or metastable atoms from gas, which depends on nature gas (helium, nitrogen, air) presence water vapor other compounds dopants. The ionizing analyte molecules are summarized, including Penning ionization, electron transfer, proton transfer ligand switching secondary hydrated hydronium ions. Presently, DBDI‐MS methods face challenge in accurate quantification gaseous analytes, limiting its broader application biological, environmental, medical realms where relative using standards is inherently complex for matrices. Finally, propose future avenues research to enhance analytical capabilities DBDI‐MS.
