Page 5: Preparation Before Use
4. Preparation before Use 4.1 The LabSen 871 pH electrode is for non-aqueous organic solvents’ pH measurement. If measuring aqueous solutions, please choose another suitable pH electrode. It is normal for this pH electrode to have a 30-60 mV deviation in electric potential compared to conventional pH electrodes, which can be eliminated by performing 2 to 3 points of calibration. -
Page 6: How To Measure
5. How to Measure 5.1 Measure in water-miscible organic solvents (e.g. methanol, ethanol, ISPA) 5.1.1 Make sure to use 1M LiCl as the electrolyte in LabSen 871 pH electrode. 5.1.2 Transfer your sample solution to an empty sample storage vial and twist it onto the electrode tight (see Graph-4). -
Page 7: How To Clean The Electrode
5.2 Measure in water-immiscible organic solvents (e.g. hexane, chloroform, toluene, etc.) 5.2.1 Replace the electrolyte to 3M KCl in LabSen 871 pH electrode. 5.2.2 Take the sample of water-immiscible organic solvents and deionized water in a separating funnel and mix vigorously. The ratio of the organic solvent sample to water can be 1:1 or as per specified method. -

6.2 After measurement in water-miscible organic solvents (e.g. methanol, ethanol, ISPA, etc.), you can choose to clean it directly with distilled or deionized water. Use a soft brush to remove the contaminants if necessary. 6.3 After measurement in water-immiscible organic solvents (e.g. hexane, chloroform, toluene, etc.), the electrode can be cleaned with ethanol, toluene, or acetone. -

solution (SKU: AI1107). Rinse off the vial and replace the soaking solution if it’s contaminated or insufficient. The electrode should never be stored in pure water such as deionized or distilled water. 8.2 The connector of the electrode should be kept clean and dry. If contaminated, please clean it with medical cotton and isopropyl alcohol and blow-dry it to prevent short circuit of the electrode or slow response of the electrode. -
