Total Organic Carbon Analyzer	Appendix

Appendix

A.1Specifications

Measurement Methods: TC (Total Carbon) – UV/Persulfate

Oxidation

TOC (Total Organic Carbon) acidification and sparging to eliminate inorganic carbon interference.

Temperature: 25o C ± 5o

Measurement Ranges: 0-10 through 0-10,000 ppm, full scale (std.)

Note: Range changes often require carrier gas adjustments. The Model 6750 uses the precision of computer controlled mass flow controllers to eliminate operator error and the use of inaccurate mechanical flow meters.

Display:	Windows with Paperless Chart Recorder
	2 Line LCD
Data Handling:	RS-232C, RS-485
Analog Output:	4-20mA
Alarms:	Two concentration alarms
	One master fault alarm

Performance:

Response Time: Dependant upon application

Repeatability: +2% FS (std. Dev. 1 sigma)

Zero/span stability: +2% FS (at 25o C)

Linearity: +2% FS
