Aurora 1030W

The Aurora 1030 line of TOC analyzers from OI Analytical includes instrument configurations for laboratory and process monitoring, employing 100 °C persulfate wet oxidation or thermal combustion techniques.

The Aurora 1030 line incorporates several noteworthy innovations and can be equipped with parallel reactors allowing concurrent sample processing for increased analytical throughput. The unique 1030D Dual Mode TOC analyzer allows sample processing by wet oxidation or thermal combustion using the same instrument.


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.

Tested & Approved

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, groundwater / surface water, process water, boiler feed water and condensate, metal plating solutions, and ultrapure water.
