3 Overview The R8111 Electrode is a silver-silver chloride reference electrode for use in the laboratory. It should be used with a 3200P ph meter, a 3200I Ion meter, or similar meters. WARNING Use this electrode according to the operating manual to avoid personal injury. WARNING The electrode solution can cause chemical burns or illness if it is taken orally or contacted by human skin. Use protective clothing or gloves to avoid contact. In case of contact, rinse contacted area with tap water or deionized water thoroughly. CAUTION The electrode body material is glass. Handle with care to avoid damage to the instrument.

6 Operation Preparation 1 Remove the storage bottle from the electrode. Store the bottle and cap upright for future use. 2 Rinse the measuring tip with distilled or deionized water. 3 Hold the electrode with the measuring tip downwards and swing it several times. 4 Unplug the filling hole. Measurement 1 Connect the electrode to the meter. Enter the temperature of the calibration solution according to the meter operating manual. 2 Soak the measuring tip in calibration solutions in sequence. Calibrate the electrode according to the meter operating manual. 3 After calibration, soak the measuring tip in sample solution. When the reading becomes stable, read the value from the meter. Operating hints The main materials of the electrode measuring tip are glass and ceramic frit. Ensure the sample solution will not damage the measuring tip before measurement. During measurement, the level of reference filling solution (p/n ) in the electrode should be above the level of the sample solution. Small white crystals or powder that forms on the electrode during measurement or transportation is harmless and does not affect the performance of the electrode. Rinse the reside from the electrode with tap or deionized water. Do not apply force onto the electrode cap, cable, or cable interface. Keep the cable interface dry. 6 R8111 Reference Electrode

7 Maintenance Exchange of the reference filling solution 1 Siphon the electrode reference filling solution and add fresh reference filling solution (p/n ) until the level is 5 mm below the filling hole. 2 Repeat several times. Cleaning of inorganics Soak the measuring tip in 0.1 mol/l HCl or EDTA solution for 15 minutes. Cleaning of organics Soak the measuring tip in absolute ethyl alcohol or other solvent that can dissolve organics for 15 minutes. Cleaning of protein precipitation Storage 1 Soak the measuring tip in 0.1 mol/l HCl solution that contains 1% pepsin for 15 minutes. 2 Exchange the reference filling solution and soak the measuring tip in reference filling solution for 2 hours. For any other problems during electrode use, contact your Agilent Technologies customer service representative. 1 Rinse the measuring tip. 2 Plug the filling hole and install the electrode storage bottle and cap onto the electrode body in sequence. To protect the measuring tip, keep 5 10 mm between the bottom of storage bottle and the electrode measuring tip. 3 Screw the storage bottle cap of the electrode until finger tight. 4 Place the bottled electrode in the storage box and store at ambient temperature in a dry location.
