Aurora 1030C TOC Analyzer

Aurora 1030C TOC Analyzer


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.


Test Methods Supported by the Aurora 1030C TOC Analyzer

The high temperature combustion technique has been approved and adopted in numerous regulatory compliance methods, standards, and norms for water quality testing.
