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.

key components and the innovative SCWO oxidation technique.

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.

InnovOx On-Line Analyzer Details

Accessories and Options

Air Purifier

The Air Purifier removes CO2 from the air so the Analyzer can
use house air as the compressed gas source.

Filter Panel

This accessory filters one sample
stream, and it is automatically
cleaned by back flushing with
compressed air. The Filter Panel is
adjustable for various particulate
levels.

Fail-Safe Accessory

Sensors detect when the flow rate of each sample stream
stops or consumables need replenishing.

IP56

The IP56 configuration protects the Analyzer from water
spray and dust that would interfere with its operation.

NEMA 4X

The NEMA 4X enclosure protects the instrument from
corrosive environments.

Other Accessories

Other accessories include a mounting stand, a sample
peristaltic pump, and multi-stream (2, 5) configurations.
