The Aurora 1030W TOC Analyzer uses the persulfate chemical oxidation technique to analyze organic contamination levels in liquid samples with reliability and accuracy. 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 at a rate of up to 300 samples in 24 hours. The reaction chamber is automatically and thoroughly rinsed between each analysis to eliminate the risk of cross contamination. This procedure also ensures that a low background is maintained, which is essential for very low TOC levels.
