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.
