Aurora 1030D Total Organic Carbon Analyzer The Aurora 1030D is a dual oxidation mode total organic carbon (TOC) analyzer that performs high temperature combustion and heated persulfate wet oxidation on the same instrument. Versatility for Maximum Capability Heated Persulfate Wet Oxidation Virtually all organic compounds dissolved in water can be oxidized by heated sodium persulfate (Na2S2O8). In wet oxidation mode the 1030D reaction chamber is thoroughly rinsed between analyses eliminating residue from the previous sample and ensuring a low system background is maintained for high sensitivity TOC measurements. High Temperature Combustion High temperature (680 °C) catalytic combustion is most effective for samples containing high molecular weight, difficult-to-oxidize organics (e.g.; humic acid) at levels > 500 ppb C. The patented* two chamber combustion tube of the 1030D contains a bed of quartz in the first chamber to protect platinum catalyst in the second chamber from deposition of non-combustible constituents. This design extends catalyst life, ensures consistent oxidation conditions, and reduces instrument maintenance costs. * Patent: US 7,306,770 B2 High Temperature Combustion Tube Wet Oxidation Reaction Chamber
