Trace Oxygen AnalyzyzerOperations 4.0Operations4.1 Filling the ReservoirThe reservoir is located on the right side of the analyzer case.1) Insure that the cap on the drain spout is securely tightened.2) Remove cap from fill port on top of reservoir.3) Pour distilled water into reservoir until it is half full (about onequart). The water will automatically flow into the humidifiercolumn.4) Replace cap on fill port and securely tighten. A missing or loosecap will permit the sample to vent into the analyzer case.4.2 Detector CellThe cell is located in the heated compartment on the left side of theanalyzer case, as shown in Figure 6. To open the compartment, unscrew thecaptive knurled knobs at the top and bottom of the compartment and removethe plastic window.4.2.1 Cell PackagingThe cell is packaged separately from the analyzer. It is filled withdistilled water to prevent oxidation of the electrodes from exposure to theatmosphere. The cell should be left filled with the distilled water until theanalyzer is installed and ready for operation. The cell should not be exposedto the atmosphere for any prolonged duration.4.2.2 ElectrolyteThe cell electrolyte is Teledyne Type A, used in applications wherethere is a complete absence of acidic anhydrides (CO 2, SO 2) in the samplegas. Type A electrolyte is a 10% solution (w/v) of reagent-grade potassiumhydroxide (KOH) in distilled water.TELEDYNE ELECTRONIC TECHNOLOGIESAnalytical Instruments4-1
