OI Analytical Aurora 1030W TOC Analyzer

Dissolved Inorganic Carbon (DIC) and Dissolved Organic Carbon (DOC)

Significantly expand sample range and increase throughput with the Aurora 1030W TOC Analyzer, an instrument specifically designed for analyzing organic contamination levels in aqueous samples by the heated persulfate wet oxidation technique.

The Aurora 1030W TOC Analyzer uses the proven heated persulfate wet oxidation technique to analyze organic contamination levels in liquid samples. The instrument can be programmed and calibrated to analyze samples containing organic carbon at levels as low as 10 ppb and as high as 30,000 ppm. In addition to its wide range, the Aurora 1030W has an extremely high daily throughput. Up to 300 samples can be analyzed in a 24-hour period (dependent on method and application).

The reaction chamber of the Aurora 1030W is thoroughly rinsed between analyses to eliminate residue from the previous sample. This ensures the Aurora 1030W maintains the low system background necessary for high sensitivity TOC measurements. This contrasts with combustion TOC analyzers in which residual salts accumulate on catalyst surfaces, degrading oxidation efficiency and causing higher blanks and background contamination.

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.

The Aurora 1030W TOC Analyzer is ideal for the following applications: drinking water, pharmaceutical cleaning validation, municipal wastewater, ground water/surface water, process water, boiler feed water and condensate, metal plating solutions, and ultrapure water.

When a 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.

δ13C in dissolved inorganic carbon (DIC) in salt and fresh water by acidification

δ13C in dissolved organic carbon (DOC) in fresh water by sodium persulfate oxidation

The system is fully automated for the measurement of 88 samples. The Aurora 1030W TOC analyzer is sold separately through OI.
