Page 5: Chapter 1: Getting Started
It is evident that a fast response, easy to operate and maintain, device has recognizable benefits for the user. The Thornton 550 Total Organic Carbon Analyzer provides a faster and easier method of on line measurement. As its predecessor, the 502P, the 550 TOC analyzer units offers the widest dynamic water quality range that can be measured without cumbersome reagents or accessories. -
Page 6: Principle Of Operation
PRINCIPLE OF OPERATION The Thornton 550 TOC Analyzer measures Total Organic Carbon in pure and ultrapure water based on differential conductivity. This difference in conductivity is used to determine the amount of organic carbon present. Flow Pressure Flow UV Oxidation... - Page 7 residence time in the oxidation chamber of less then one minute. The conductivity measurements are continuous; therefore, response time is directly related to the residence time of the sample in the oxidation chamber. Values of TOC, resistivity (or alternatively conductivity or uncompensated conductivity), and temperature are displayed on the LCD screen of the instrument.

Page 8: Chapter 2: Installation / Set-Up
CHAPTER 2: INSTALLATION / SET-UP LOCATION The Thornton 550 TOC Analyzer is to be installed in a dry environment with a relative humidity <80% (non-condensing) and with ambient temperature between 5 and 40°C (41 to 104°F), on a flat, horizontal surface. The sample inlet line should be fitted with an isolation valve. -
Page 9: Analog Output
Communication specifications for this port: 9600 baud; 1 stop bit; no parity; 8-bit data. Mettler-Toledo Thornton, Inc. supplies a small format thermal printer as an optional accessory. A straight-through 9 pin, male or female, sub-D cable is provided with this printer. -
Page 10: Start-Up
Observe the flow rate from the flow meter on the front panel of the Thornton 550 TOC Analyzer. Adjust the flow rate to the maximum setting by means of the flow adjustment knob, located at the top of the flow meter. If not... - Page 11 After rinsing, use the flow adjustment knob to set the flow to 20 ml/min. CAUTION: Even if no pressure adjustment is required (which is the usual case); the cover should be removed so that the analyzer can be checked for water leaks, as any leak could be a source of error in the readings and also could lead to damage or failure of the unit.

Page 28: Chapter 7: Calibration
CHAPTER 7: CALIBRATION Four aspects of Calibration are covered in this section. • Analog Output Calibration. This procedure is used to calibrate the analog output loop. • Auto Zero Calibration. This is a procedure, performed by the monitor itself, to obtain zero readings of the two TOC sensors and correct for any zero drift. -
Page 29: Auto Zero Calibration
BOARD CALIBRATION This section describes a procedure to verify the functionality and accuracy of the electronics within the instrument. The Thornton 550 TOC Analyzer has two sensors for TOC measurement and one sensor for measurement of the incoming water sample. - Page 30 Stop the measurement and remove the top cover.

Thornton 770MAX system. The measuring point of the 770MAX should be close to the connection point for the Thornton 550. TOC verification/calibration can be performed a number of ways. - Page 34 A second, more extensive TOC calibration, subjects the test unit to a known TOC level. A sample is prepared by adding some suitable reagent into low TOC water, to prepare a sample with known TOC level. Run the calibration sample through the unit until stable readings are achieved. The instrument value can be adjusted in the following manner.

Page 35: Chapter 8: Advanced Configuration
CHAPTER 8: ADVANCED CONFIGURATION ADVANCED START UP METHODS The CONFIGURATION and OPERATION methods described previously should be adequate for pure and ultrapure waters (resistivity generally in the 10-18 MΩ-cm range) with relatively low levels of TOC. However, at higher levels of TOC, such as encountered in some Reverse Osmosis product water, recycle, and reclaim rinse water, an advanced configuration technique may be necessary for proper operation. - Page 36 OTHER SETUP WRITE NOTE: Changing the WRITE OFF to ON will allow changes to be the factory settings within the ‘OTHER SETUP’ menu screens. This should only be turned to ON if changes are being made. Using the NEXT key select INITIALIZE CHANGE screen. 2.INITIALIZE CHANGE Calib.
