Fast and Sensitive Measurement of Off‐Flavors in Recirculating Aquaculture Systems

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Geosmin and 2‐methylisoborneol (2‐MIB) are odor‐active compounds responsible for earthy off‐flavors in fish, creating significant quality concerns in recirculating aquaculture systems (RAS). Their extremely low odor thresholds make rapid and highly sensitive detection essential for maintaining product quality and consumer acceptance ...

Establishment of a Purge and Trap Continuous‐Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ15N and δ18O) in Water Samples by Ti(III) Reduction

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Lithium Isotopic Analysis of Spodumene by Secondary Ion Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 13, 15 July 2026.
ABSTRACT Rationale Lithium (Li) stable isotopes can provide insight into fluid–rock interaction and magmatic differentiation. Therefore, it is essential to develop an accurate and precise method to determine the Li isotope signature in spodumene.
