  • Page 18: Figure 2-1: Npoc Or Toc - Direct Method

    Theory of Operation Model 6750 To perform correct TOC analysis, the analysis system must be capable of measuring all constituents of organic carbon present in the sample: Non-Purgeable Organic Carbon (NPOC) and Purgeable Organic Carbon (POC). Correct TOC analysis must also exclude the Total Inorganic Carbon (TIC) interference.

In the TOC-True method used by the Model 6750, the analyzer actually performs both TC and TIC measurements simultaneously and continuously on the same sample.

  • Page 24: Figure 2-6: Sample Handling For Toc -Direct

    Theory of Operation Model 6750 actual measurement of the TIC, a more accurate TOC is achieved since (TOC = TC - TIC). “TOC-Direct” mode is preferred for accuracy when no or little volatiles are present. In this mode, the carbonate-free sample is extracted from the organic carbon reactor and measured directly as TOC.

    It is a pressure swing absorption PSA device requiring only electricity only to operate. Also available from Teledyne is an Instrument Air Purifier (P/N ST200019). This device can supply the oxygen demands of the instrument using facility instrument air.

  • Page 26: Inorganic Carbon Removal/Analysis

    The NPOC analysis ignores the volatile organics for a less precise NPOC analysis if organic volatiles are present. The sparger used in the Model 6750 is a gas/liquid counter-flow stripper. Actual acid addition depends on the amount of sample buffering and pH.

  • Page 27: Oxidation

    The UV reactor and persulfate reagent provide oxidation of the carbon to CO . The UV reactor consists of the following: • Mounting enclosure with viewing window • Borosilicate reactor body • Heater/Temperature sensor • UV Lamp • Miscellaneous fittings and clamps Teledyne Analytical Instruments...

  • Page 28: Figure 2-9: Oxidation Reactions

    Theory of Operation Model 6750 The construction of the patented UV reactor in the Model 6750 affords superior oxidation by precisely controlling the sample temperature, adding a precise amount of ultra-pure persulfate reagent (P/N ST40000) and precisely controlling the carrier gas flow rate.

  • Page 29: Ndir Co Gas Detection

    The key component for reliable TOC analysis is the precise and interference-free detection of CO . The Model 6750 NDIR unit requires very little maintenance because of its ability to handle the corrosive gases generated in TOC analysis. This is due in part to its non-reflective borosilicate sample cell.

  • Page 30: Electronic Signal Processing, Display And Control

    Theory of Operation Model 6750 requires no wall reflectivity and is completely resistant to corrosive gases. The NDIR unit requires no optical chopper motor or mechanical devices but utilizes a single flashing infrared source to optically “chop” the infrared (IR) beam, which equally irradiates CO /reference detectors.
