Important Notice
This instrument provides measurement readings to its user, an d serves as a to ol by whic h
valuable data can be gathered. The information provided by the instrument may assist the user
in eliminating potential hazards caused by his process; however, it is essential that all
personnel involved in the use of the instrument or its interface, with the process being
measured, be properly trained in the process itself, as well as all instrumentation related to it.
The safety of personnel is ultimately the responsibility of those who control process
conditions. While this instrument may be able to provide early warning of imminent
danger, it has no control over process conditions, and it can be misused. In particular, any
alarm or control systems installed must be tested and understood, both as to how they
operate and as to how they can be defeated. Any safeguards required such as locks, labels,
or redundancy, must be provided by the user or specifically requested of TI/AI at the time
the order is placed.
Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser
is responsible for the training of personnel, for providing hazard warning methods and
instrumentation per the appropriate standards, and for ensuring that hazard warning devices
and instrumentation are maintained and operated properly.
Teledyne Instruments/Analytical Instruments, the manufacturer of this instrument, cannot
accept responsibility for conditions beyond its knowledge and control. No statement
expressed or implied by this document or any information disseminated by the
manufacturer or its agents, is to be construed as a warranty of adequate safety control under
the user’s process conditions.

Introduction
1.1 Overview
Teledyne Analytical Instruments (TAI) offers a variety of Total
Organic Carbon (TOC) analyzers to serve a wide range of applications.
The Model 6700C High Temperature Combustion TOC Analyzer
provides accurate and reliable on-line TOC and TN analysis and is
configured to provide maximum utility using an advanced Micro s of t
Windows based CE computer with touch screen.
This manual includes all necessary information to help you install,
operate and service your Analyzer. The analyzer is designed for easy
Operator Maintenance and does not normally require field service.
The Windows-based CE operator interface provides easy, fast and
reliable analysis. This manual includes all necessary information to help
you install, operate and service your Analyzer.
The Model 6700C TOC-True Analyzer is designed for easy
operation and maintenance. Particular attention has been devoted to the
design, whereby any module can be replaced by the operator within 15
minutes. Components such as the NDIR units have been specifically
designed with no moving parts and use a corrosion resistant design to
further reduce maintenance tasks.
The analyzer is suitable for both General Purpose and/or Hazardous
Area classifications, if properly configured with required safety
equipment.
Operating the analyzer is easy. It uses a standard, industrial
Windows CE computer programmed for complete automatic control
(there are no operator manual adjustments). Operators are advised to
study pertinent chapters in this manual to fully utilize the capabilities of
the analyzer and avoid problems that could be associated with any
instrument.

Operational Theory Model 6700C TOC
The Analyzer is designed for monitoring of Total Organic Carbon
(TOC) in water. This intended use involves carefully following the
instructions provided in this manual and observing all indicated
warnings, hints and instructions.

High Temperature Combustion Operational Theory
Operational Theory
2.1 Measurement Principle
Refer to Figure 2-1.
The Injector is connected with all possible flow paths and separated
from sample and reagent liquids by a 10 ml volume loop. One end of the
volume loop is connected to the injector, the other is connected to the
center port of a 10 port Rotary Valve.
A typical sequence of events for the injection unit for measurement
of TOC is as follows:
The Rotary Valve will be engaged, opening a flow path to the drain
line of the analyzer. The Injector is then sent to the home or empty
position.
The DI Valve is turned on and a small amount of DI is then picked
up by the Injector. The DI Valve is then turned off and the Rotary Valve
is turned to the Acid Port where the Injector pulls a small amount of acid
into the loop. The Rotary Valve is then turned to the sample port and
sample is pulled into the loop. The Rotary Valve is turned to the Sparge
Port and the Injector then pushes the sample and acid to the sparger
through the Sparger Port, where the pH is lowered to approximately 2.0
and inorganic carbon is removed.
After the sparge time is completed, the Injector pulls the inorganic
free sample volume from the sparger. The Rotary Valve is then turned to
the Reactor Port. The Injector pumps the sample into the reactor at a
flow rate of one (1) drop in approximately seven (7) seconds.
The sample is oxidized in the High Temperature Furnace where
organic carbon is converted to CO2 and the gases are directed to a cooler
condenser where excess water is removed, and then on to the NDIR
where the CO2 is measured and TOC is determined. The gases are then
passed to vent.
