Establishment of a Purge and Trap Continuous-Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ<sup>15</sup>N and δ<sup>18</sup>O) in Water Samples by Ti(III) Reduction. [PDF]

open access: yesRapid Commun Mass Spectrom
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.
