Sievers InnovOx
Laboratory and On-Line TOC Analyzers
Overview
GE Analytical Instruments designed the Sievers* InnovOx
Total Organic Carbon (TOC) Analyzers to provide industryleading sample handling robustness and instrument uptime
for process, environmental, and wastewater organic carbon
analysis. Available in both Laboratory and On-Line models,
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 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 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 (see table on
page 4) with unprecedented reliability.
• Easy Operation—The InnovOx On-Line offers
preset protocols for easy startup. Both OnLine and Laboratory models have intuitive
color touch-screen interfaces, and operate
immediately without any necessary heater
warm-up or detector stabilization.
Fact Sheet
• 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)—Allows users to
remotely monitor and control Analyzer operations and
results using a Web-based interface via the instrument’s
Ethernet port.
• User-configurable alarms and outputs (On-Line)—No-
tifies user of water system events and enables remote
monitoring of analysis results and performance.

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 sample coil delivery
system which prevents syringe contamination.
Supercritical Water Oxidation (SCWO)
Using a patented SCWO technique (see sidebar below), 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 oxidation of TOC to carbon
dioxide, even in the presence of chloride and other inorganic species that negatively interfere with traditional
oxidation techniques.
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.

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 (770 °F) and 22.1 mPa (3,200 psi). These conditions enable rapid
and complete oxidation of organic carbon to CO2.
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.
