Warranty

This equipment is sold subject to the mutual agreement that it is warranted by us free from

defects of material and of construction, and that our liability shall be limited to replacing or

repairing at our factory (without charge, except for transportation), or at customer plant at

our option, any material or construction in which defects become apparent within one year

from the date of shipment, except in cases where quotations or acknowledgements provide

for a shorter period. Components manufactured by others bear the warranty of their

manufacturer. This warranty does not cover defects caused by wear, accident, misuse,

neglect or repairs other than those performed by TI/AI or an authorized service center. We

assume no liability for direct or indirect damages of any kind and the purchaser by the

acceptance of the equipment will assume all liability for any damage which may result from

its use or misuse.

We reserve the right to employ any suitable material in the manufacture of our apparatus,

and to make any alterations in the dimensions, shape or weight of any parts, in so far as

such alterations do not adversely affect our warranty.

Important Notice

This instrument provides measurement readings to its user, and serves as a tool by which

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 Microsoft

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

Teledyne Analytical Instruments 16

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

Teledyne Analytical Instruments 17

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 CO

2

and the gases are directed to a cooler

condenser where excess water is removed, and then on to the NDIR

where the CO

2

is measured and TOC is determined. The gases are then

passed to vent.

Installation and Startup

The Model 6700C is often configured for a specific application as

requested by the customer. Optional equipment and any application

specific configuration of this instrument will be described in an

addendum to this manual. Please check the front of this manual for any

addenda that may be included.

3.1 Installation

Installation of the Total Organic Analyzer includes:

1. Unpacking

2. Mounting

3. Gas Connections

4. Electrical Connections

5. Testing the System

6. Unpacking the Analyzer

The analyzer is shipped with all the materials you need to install

and prepare the system for operation. Carefully unpack the analyzer and

inspect it for damage and immediately report any damage to the

shipping agent.
