Aurora 1030W TOC Analyzer


Aurora 1030W TOC Analyzer


The Aurora 1030W Total Organic Carbon (TOC) Analyzer uses the proven heated persulfate wet oxidation technique to analyze organic contamination levels in aqueous samples.


Virtually all organic compounds dissolved in water can be oxidized by heated sodium persulfate (Na2S208). Concentrated solutions (1 or 1.5 M) can effectively oxidize organic matter present in the form of colloids, macromolecules, and suspended solids.


The Aurora 1030W can be programmed and calibrated to analyze samples containing organic carbon at levels as low as 10 ppb and up to 30,000 ppm. Depending upon method and application, up to 300 samples can be analyzed in a 24-hour period.

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 Aurora 1030W can be equipped with a number of instrument options and automation accessories to improve sample throughput and productivity.
· An optional second oxidation chamber supports concurrent sample processing.
· An 88-position rotary autosampler fits directly underneath the 1030W to conserve bench space.
· ATOC software provides 21 CFR Part 11 compliant data handling, security, auditing, and reporting capability.
· An optional validation package provides complete IQ / OQ / PQ documentation to validate an Aurora 1030W for use in pharmaceutical GLP/GMP applications.
· Multi-stream sampling module for at-line monitoring of up to four process streams.
· 1030S Solids Module operates in conjunction with a 1030W analyzer to combust solid materials for analysis of TC or TOC.
· Accessory kits to configure and interface a 1030W to an Isotope Ratio Mass Spectrometer (IRMS) or Cavity Ring Down Spectrometer to measure TOC and the δ13C stable isotope ratio.
