The OI Aurora 1030W TOC Analyser ensures high-throughput analysis of liquid samples for organic contamination by the heated persulfate wet oxidation technique. The additional coupling with a Picarro δ13C-CO2 analyser extends scope of capability to also test δ13C.

• Measurement of δ13C in dissolved inorganic carbon (DIC) in salt and fresh water by acidification
• δ13C in dissolved organic carbon (DOC) in fresh water by sodium persulfate oxidation

This combination removes the need for expensive and difficult to maintain isotope ratio mass spectrometry systems for δ13C
