Rapid 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 ...
