Heated Persulfate Wet Oxidation

The heated persulfate oxidation technique has been approved and adopted in numerous regulatory compliance methods, standards, and norms for water quality testing, including: Standard Method 5310C, USEPA 415.3, USP <643> / EU 2.2.44, ASTM D 4779 and 4839, USEPA-DBPR, USEPA-SPCC, ISO 8245, and EN 1484.

In wet oxidation mode the 1030D reaction chamber is thoroughly rinsed between analyses to eliminate residue from the previous sample. This ensures a low system background necessary 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. Our 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.
