SERIES 6700

Product catalog summary

Overview
The Teledyne Series 6700 Total Organic Carbon (TOC) Analyzers are designed for a range of industrial applications, focusing on process and environmental compliance. The analyzers utilize a robust Infrared CO2 detector for interference-free detection and are available with optional Microsoft Windows™ based touch screen control.

TOC Methods

UV / Heated Persulfate Method: Suitable for low to moderate salt-free samples, requiring minimal maintenance.
Ozone/Hydroxyl Radical Method: Effective for difficult to oxidize samples, especially in undiluted acids or industrial salts over 26%.
Combustion Method: Ideal for high TOC concentration samples with industrial salts less than 1%.
Ultrapure Method: Provides high accuracy in the parts per billion range without pumps, suitable for applications under 1000 ppb TOC.

Configurations
Custom solutions are available for various environments, including hazardous and outdoor settings, with options for sample systems, oxygen generators, and NEMA enclosures.

General Features

Compliance with EPA, ASTM, and other standards for continuous TOC analysis.
Features include NPOC analysis, rapid response, and low maintenance.
Available with onboard Microsoft Windows CE computer or menu-driven LCD display.

Installation Requirements

Electrical source: 110/220 VAC 10 amp service.
Sample flow: Minimum of 10 ml/minute.
CO2-free air or oxygen source: Maximum flow rate of 300 cc/minute at 15 psig.

TOC Measurement Basics
TOC measurement involves differentiating between Total Carbon (TC), Total Inorganic Carbon (TIC), and Total Organic Carbon (TOC). The document outlines methods for measuring TOC, including the difference method and direct NPOC method.

Subsystems
The Series 6700 TOC Analyzer consists of five subsystems: sample handling, inorganic carbon removal or analysis, oxidation, NDIR CO2 gas detection, and electronic signal processing.

Applications
Applicable for boiler feedwater, cooling water, wastewater, river water, and process control, complying with standards like EPA 415.1 and ASTM D 4839-88.

Specifications

Range: Varies by method, from 0-10 ppm to 0-25,000 ppm.
Sensitivity and Repeatability: Governed by repeatability specification, typically ±2% to ±3% of full scale.
Response Time: Varies by method, from 5 to 10 minutes.
Power Supply: 110/220 VAC 10 amp service recommended.

Options

Dual NDIRs, portable calibration gas kit, and start-up kit.
Additional features like auto-calibration, auto-clean, and pumpless reagent saver package.

Warranty
The instrument is warranted for one year against defects in material or workmanship.

he Series 6700 covers a complete range of Total Organic Carbon (TOC) Analyzers capable of addressing a variety of industrial applications for process and environmental compliance purposes. Depending on the application, TAI can recommend which technique is best suited to continuously detect TOC within your process. The robust and reliable Infrared CO2 analyzer is the heart of each design. It provides specific, interference-free CO2 detection, has no moving parts, and is extremely easy to access and service, as required. Each configuration is available with an optional Microsoft Windows™ based...

Operational Theory Selecting the appropriate TOC method for an application requires a cost / performance trade-off analysis. TC = Total Carbon, including NPOC, POC, TIC TIC = Total Inorganic Carbon (H2CO3 + HCO3 - CO3-2 + CO2) TC - which includes NPOC, POC, TIC (interference) TOC-True = Total Organic Carbon NPOC - which includes NPOC only and no TIC interference or detection of POC NPOC = Non-Purgeable Organic Compound TOC - which includes NPOC and POC, but no TIC interference POC = Purgeable Organic Carbon (interchangeable with VOC) To perform correct TOC analysis, the operator must measure...
