OverviewGE Analytical Instruments designed the Sievers InnovOx Total Organic Carbon (TOC) Analyzers to provide industry-leading sample handling robustness and instrument uptime for process, environmental, and wastewater organic carbon analysis. Available in bothLaboratory and On-Line models, the InnovOx uses aninnovative Supercritical Water Oxidation technique that offers enhanced eliability, greater ease of use, and lower maintenance than typical combustion or UV persulfate TOC analyzers.
Features and Benefits
• Wide Dynamic Operating Range — Measures up to 50,000 parts per million (ppm).
• Versatile Measurement Modes — Measures Total Inorganic Carbon (TIC), NPOC, Total Carbon (TC) and TOC by difference (TC-TIC).
• Sample Handling Robustness — Uses aninnovative Supercritical Water Oxidation(SCWO) technique to achieve superior TOC recoveries regardless of organic compounds and particulate impurities in the sample. The InnovOx can handle awide variety of traditionally difficult sample matrices, including brine, cellulose, and humic acid (see tables on pages 3 and 4) with unprecedented reliability
• Easy Operation — The InnovOx On-Line offers preset protocols for easy startup. Both On-Line and Laboratory models have intuitive color touch-screen interfaces, and operate immediately without any necessary heater warm-up or detector stabilization.
• Low Maintenance and Cost of Ownership — Robust by design, the InnovOx requires minimal operator intervention or preventive maintenance, offers up to six months’ calibration stability, and features a solid state nondispersive infrared (NDIR) detector.
• Ethernet Web browser interface (Lab model) — Allows users to remotely monitor and control Analyzer operations and results using a Web-based interface and the instrument’s Ethernet interface.
• User-configurable alarms and outputs (On-Line model) — Notifies user of water system events and enables remote monitoring of analysis results and performance.
• Food and Beverage
• Chlor-alkali Chemistry
• Environmental Labs
• Municipal/Industrial Wastewater
• Pulp and Paper
• Brine and Seawater
• Unconventional Oil & Gas
The innovOx features three main steps,each with significant process innovations:
Sample Handling and Reagent Mixing
The InnovOx ensures superior sample representation and accuracy by processing a large sample volume and thoroughly agitating the sample in the Sample Mixing Chamber. The sample and reagents are added through a unique sample coil delivery system which prevents syringe contamination.
Supercritical Water Oxidation (SCWO)
Using a patented SCWO technique (see sidebar at right), the Sievers InnovOx takes the water sample to a supercritical state by increasing the temperature, and subsequently the pressure, within the reactor. The properties of supercritical water enable an ultra-efficient, rapid oxidation of organic carbon to carbon dioxide, even in the presence of chloride and other inorganic species that negatively interfere with non-SCWO oxidation.
The InnovOx uses a highly stable, nondispersive infrared (NDIR) detector. Unlike other NDIR detectors, the InnovOx NDIR has no moving parts, and features tight temperature control of the IR source and detector. Visit the Library at www.geinstruments.com to see animations of these key components.
Supercritical Water Oxidation (SCWO)
Supercritical Water Oxidation (SCWO) was originally developed to treat large volumes of aqueous waste streams, sludges, and contaminated soils. SCWO destroys organic wastes using an oxidant in water and temperatures and pressures above the critical point of water—375 °C and 3,200 psi. These conditions enable rapid and complete oxidation. Today, SCWO research and development is focused on treating a variety of toxic and hazardous organic wastes. GE Analytical Instruments is the first company to use this technique in a commercial laboratory TOC instrument.
InnovOx Laboratory Model Details
Accessories and Options
For high-volume laboratory applications, the InnovOx can be used with the GE Autosampler. It can handle up to 120 35-mL sample tubes or up to 63 40-mL or 60-mL vials in one protocol. An optional stirring station creates a homogeneous mixture for analysis during the sampling process.
The Air Filter can be used to purify ambient air and pressurize it sufficiently for use as sparge and carrier gas. It easily attaches to the back of the InnovOx Laboratory, and allows the Analyzer to be used in place of external carrier gas cylinders.
Sievers Certified Standards and TOC Vials
Sievers Certified Reference Materials are available for InnovOx calibration and verification needs, as well as reliable and economical 40-mL and 60-mL TOC vials.
