OI Analytical Aurora 1030C TOC Analyzer

The Aurora 1030C TOC Analyzer processes aqueous samples for analysis of the total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content of the samples. Samples containing 100 ppb to 30,000 ppm of organic carbon can be analyzed. The Aurora 1030C supports USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, and EU Methods. Depending upon the protocol employed, up to 300 samples per 24-hour period can be analyzed, and in excess of 100,000 samples per year.

The Aurora 1030C employs high temperature (680 °C) catalytic combustion to oxidize and convert organic compounds present in aqueous samples to CO2 for measurement by a solid state non-dispersive infrared (SS-NDIR) detector.

The high temperature combustion technique is most effective for analysis of samples containing high molecular weight, difficult-to-oxidize organics (e.g; humic acid) at levels > 500 ppb C.

The Aurora 1030C is equipped with a patented* two chamber combustion reactor that overcomes problems associated with TOC analyzers that use a single chamber reactor. The first chamber of the 1030C reactor contains a bed of quartz to protect the platinum catalyst in the second chamber from deposition of noncombustible constituents, and ensures consistent oxidation conditions for stable blanks. This reactor design extends catalyst life and reduces instrument maintenance costs.
