Total Organic Carbon Analyzer	Introduction

Introduction

Teledyne Model 6750 Total Organic Carbon Analyzer provides accurate and reliable on-line TOC analysis with Windows™ CE Operation, using the UV/Heated Persulfate Oxidation Method.

This manual includes all necessary information to help you install, operate and service your Analyzer.

The Model 6750 TOC Analyzers have been 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 unit have been specifically designed with no moving parts and use a corrosion resistant design to further reduce maintenance tasks.

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. The Model 6750 TOC is shown in Figure 1-1.

1.1 Main Features of the Analyzer

The Model 6750 TOC Analyzer is sophisticated, yet simple to use. The main features of the analyzer include:

•TC (Total Carbon) analysis

•NPOC (Non-purgeable organic carbon) analysis

•TOC-True Analysis (including volatile organics)

•Microsoft Windows Touch Screen Computer with Paperless Chart Recorder

•Two alarm levels

•One Master Fault Alarm

•3 analog 4-20 mA outputs
