The Aurora 1030W TOC Analyzer processes aqueous samples for analysis of total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content. Using heated persulfate oxidation technology, samples containing 2 ppb to 30,000 ppm of organic carbon can be analyzed. Up to 300 samples per 24-hour period can be analyzed. The Picarro δ13C-CO2 analyzer is coupled with an Aurora 1030W TOC Analyzer from OI, the system provides δ13C measurements of the dissolved carbon in water samples.
