Source identification of N2O produced during simulated wastewater treatment under different oxygen conditions using stable isotopic analysis by T Azzaya, Sakae Toyoda, Naohiro Yoshida, Hiroshi Shiomi, Rina Kouno

“…We investigated the N₂O production mechanisms during batch experiments that simulate wastewater treatment with activated sludge under various dissolved oxygen (DO) concentrations by stable isotope analysis. About 125mL of water was sampled from 30L incubation chamber for several times during the incubation, and concentration and isotopomer ratios of N₂O and N-containing species were measured using gas chromatography/isotope ratio mass spectrometry (GC/IRMS). …”

Plants or bacteria? 130 years of mixed imprints in Lake Baldegg sediments (Switzerland), as revealed by compound-specific isotope analysis (CSIA) and biomarker analysis by M. Lavrieux, A. Birkholz, K. Meusburger, K. Meusburger, G. L. B. Wiesenberg, A. Gilli, C. Stamm, C. Alewell

“…According to this aim, we applied two approaches, namely compound-specific isotope analysis (CSIA) of long-chain fatty acids (FAs) and triterpenoid biomarker analysis, to a eutrophic lake, Lake Baldegg, and its agriculturally used catchment (Switzerland). …”

A Simple Elemental Sulfur Reduction Method for Isotopic Analysis and Pilot Experimental Tests of Symmetry‐Dependent Sulfur Isotope Effects in Planetary Processes by Mang Lin, Mark H. Thiemens

“…Developing different chemical protocols for isotopic analysis is consequently of utility. The reduction of S0 to hydrogen sulfide (H2S) is the first step of the fluorination method for isotopic analysis, but existing S0 reduction methods require relatively long chemical reagent preparation time. …”

Retroconversion is a minor contributor to increases in eicosapentaenoic acid following docosahexaenoic acid feeding as determined by compound specific isotope analysis in rat liver by Adam H. Metherel, Raphaël Chouinard-Watkins, Marc-Olivier Trépanier, R. J. Scott Lacombe, Richard P. Bazinet

“…Afterwards, livers were collected and the natural abundance 13C-enrichment was determined by compound specific isotope analysis (CSIA) of liver EPA by isotope ratio mass-spectrometry and compared to dietary ALA and DHA 13C-enrichment. …”

Mobility in the Atacama Desert, northern Chile, in the Late Intermediate Period (AD 900–1450): A re-evaluation using stable isotope analysis by Santana-Sagredo, F, Lee-Thorp, J, Schulting, R, Uribe, M

“…The widespread application of these two models, however, suffers from a lack of supporting archaeological evidence. Stable isotope analysis provides a more direct approach for studying both diet and mobility patterns, complementing material culture studies. …”
