Toward Metabolomics Analyses With Combined Capillary Vibrating Sharp‐Edge Spray Ionization and Atmospheric Pressure Chemical Ionization

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale The varied properties of metabolomics components dictate the tools used in mass spectrometry (MS) characterization including the selection of the ionization source. However, the ionization of select compounds limits characterization efficiency.

A New Approach to the Analysis of Dissolved Gases Using Passive Samplers, With Portable Mass Spectrometry and Gas Chromatography Techniques

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale Portable mass spectrometry systems such as miniRUEDI enable rapid and low‐cost field analysis of dissolved gases with high temporal resolution. However, they remain poorly suited for discrete small‐volume water samples. This study presents an approach based on passive sampling for groundwater and surface waters dissolved gases and ...

Olive Oil Quality Analysis and the Detection of Adulterations by GC‐MS With Cold EI

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 9, September 2026.
ABSTRACT Olive oil is widely consumed for its nutritional and health benefits, yet its high market value makes it vulnerable to adulteration and mislabeling. Current analytical approaches for assessing olive oil quality and authenticity rely largely on indirect analyses, such as fatty acid methyl ester (FAME) profiles, peroxide values, or UV absorbance,
