Analyzer PreparationInstallation of a NewReference Electrode1. Unpack the reference electrode (Cat. No. 210056) and its instructionsheet from the shipping box.2. Carefully remove the protective caps from the bottom and sidearm ofthe reference electrode. Save the caps for future storage of the electrode.3. Shake out as much of the fill solution as possible through the sidearm.Drain the fill solution through the sidearm or use a pipet or syringe.4. While passing the 1/8 inch tubing into electrode sidearm, slide the 1/4inch tubing over the sidearm. The outside tubing should extend 3/8 to1/2 inches over sidearm. Refer to Figure II-10.Figure II-10Reference Electrodewith Filling SolutionReference ElectrodeFilling SolutionGasketTubing Bottle AdaptorSmall 1/8” Tubing InsideBottle CapElectrode SidearmLarge 1/4” TubingCeramic Frit5. Remove the cap and fluid seal from reference electrode fill solutionbottle (Cat. No. 181073). Hold the bottle in an upright position.Check that the rubber gasket is properly aligned, and then connectthe cap end of the tubing assembly to the bottle. The 1/8 inch tubingshould extend into the bottle.6. Hold the reservoir bottle above the electrode with the bottle cap enddown. The electrode should be horizontal with the sidearm pointingup. Gently shake the electrode to allow any trapped air bubbles to riseinto the bottle as the electrode fills with solution.7. Dry off the ceramic frit on the base of the electrode with a lint-freewipe. Squeeze the bottle for a few seconds. A small amount of fillingsolution should bead up on the frit surface, indicating good fillingsolution flow. If no moisture is visible, the electrode is clogged andshould be cleaned or replaced.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideII-13
