Chapter 2: System Description
The CO produced in the sparger by the acidification of the IC, and in the reactor by the oxidation of organics, is

separated from liquid in the gas-liquid separator. Then the CO
NDIR has been especially designed for use in the InnovOx TOC Analyzer. It has no moving parts for long-term
reliability, and it is constructed with durable materials that do not require the use of consumable absorbers to
prevent attack by corrosive gases. Furthermore, the response of the NDIR is stabilized against temperature
changes by controlling the temperatures of the IR source and detector. The NDIR response also is compensated
for changes in barometric pressure, so that the InnovOx TOC Analyzer requires only infrequent recalibration.

Additional System Components

System/Controller and Electronics

Operation of the Analyzer is controlled by an advanced X86 microprocessor on the System/Controller Board,
which communicates with the other Analyzer modules over a Multipoint Low Voltage Differential Signaling (M-
LVDS) bus. Other electronic assemblies provide the interface, monitor and control functions for the Analyzer:
• Color LCD VGA display with touch panel
• Multistream module board for microprocessor-controlled selection of the sample to be measured
(This board also controls operation of the optional sample pump accessory.)
• Sample handling module board for microprocessor-controlled preparation of the sample,
reagents, and dilution water
• Gas control module board for microprocessor-controlled control of the carrier and sparge gases
• Reactor module board for microprocessor-controlled oxidation of the samples
• NDIR module board for microprocessor-controlled measurement of the CO
Sample Handling and Reactor Modules
• Input/Output board for processing digital input signals and analog and digital outputs
• Terminator board, which terminates the M-LVDS bus and provides Ethernet and USB interfaces
• Power Entry/Supply
