GE Wins Patent Approval for InnovOx TOC Technology

March 21, 2012 – Boulder, CO – The US Patent and Trademark Office has awarded five patents to GE for “Carbon Measurement in Aqueous Samples Using Oxidation at Elevated Temperatures and Pressures.” GE Analytical Instruments’ team refined an innovative technology, commonly known as Supercritical Water Oxidation (SCWO), for its Sievers InnovOx Total Organic Carbon (TOC) Analyzers. Although SCWO was originally developed to treat large volumes of aqueous waste streams, sludges and contaminated soils. GE Analytical Instruments is the first company to use the SCWO technique in a commercial TOC instrument.

The Sievers InnovOx Laboratory and On-Line TOC Analyzers run thousands of industrial process, wastewater, and environmental water samples-including brine, humic acid, and cellulose-with unprecedented uptime. The SCWO technology enables superior TOC recoveries regardless of organic compounds and particulate impurities in the sample. SCWO also removes oxidation byproducts and sample between analytical runs, eliminating frequent maintenance, such as expensive catalyst replacement.

The InnovOx detects up to 50,000 ppm, is easy to operate, and requires no external carrier gas. Preventive maintenance and calibration are recommended every six months. For more information, visit the InnovOx On-Line or Laboratory web pages at www.geinstruments.com.
