The Sievers InnovOx – Redefining Robustness in TOC Analysis

GE Analytical Instruments designed the Sievers* InnovOx Total Organic Carbon (TOC) Analysers to provide industry-leading sample handling robustness and instrument uptime for process, industrial water, and wastewater organic carbon analysis. Available in both an On-Line and Laboratory model with an optional GE Autosampler, the InnovOx uses an innovative Supercritical Water Oxidation technique that offers enhanced reliability, greater ease of use, and lower maintenance than typical combustion or UV persulfate TOC analysers.

Features and Benefits

• Wide Dynamic Operating Range — Measures from 0.5 to 50,000 parts per million (ppm).

• Versatile Measurement Modes — Measures TOC by difference (TC-TIC), Non-purgeable Organic Carbon (NPOC), Total Carbon (TC) and Total Inorganic Carbon (TIC).
• Sample Handling Robustness — Uses an innovative Supercritical Water Oxidation (SCWO) technique to achieve superior TOC recoveries regardless of organic compounds and particulate impurities in the sample. The InnovOx can handle a wide variety of traditionally difficult sample matrices, including brine, cellulose, and humic acid 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.
• Ethernet Web browser interface (Lab model) — Allows users to remotely monitor and control Analyser 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.

Key Applications

• Reuse/Reclaim (OL)
• Industrial Wastewater (Lab & OL)
• TOC/COD/BOD Correlation (Lab & OL)
• Process Control/Optimisation (Lab & OL)
• Brine/High Salt Water (Lab & OL)
• Cooling Leak Detection, Boiler Feed (OL)
• Condensate (OL)
• Surface Water (OL)

Technology and Operation
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, 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.
• NDIR Detection - 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.
