Study on Diphenylamine Oxidation by Ozone Using Atmospheric Pressure Chemical Ionization Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Diphenylamine (DPAH) derivatives, widely used as antioxidants, interact with oxygen molecules (or ozone) to form radicals at the amine group. Although the antioxidation mechanism involves radical processes, separating these radicals using chromatography is challenging. Methods Rapid oxidation of DPAH was achieved through ozonation in

A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ15N Integrity of Nitrogen‐Poor Samples

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

CO2 and N2O Emissions From Vehicles in Seoul Megacity, South Korea: Insights From Mixing Ratio and Stable Isotope Ratios

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Vehicular traffic is a major source of anthropogenic greenhouse gases in megacities; however, real‐world constraints on vehicle‐derived N2O emissions and their isotopic characteristics remain limited. Methods Air samples were collected from three tunnels and urban background sites (a university campus and mountain) in Seoul, South ...
