    Appendix: pH Theory XL15, 20, 25, 50 and 60 meters At 25°C in pure water, the concentration of hydronium ions is extremely small, 1 x 10 Moles/liter, and balanced by an equal concentration of hydroxyl ions. The equilibrium constant, Kw of water is the product of the hydronium ion and hydroxyl ion concentrations: –...

    Appendix: pH Theory XL15, 20, 25, 50 and 60 meters pH Measurement The pH value of a sample can be determined in several ways. These include the use of organic dyes which change color in certain pH ranges. The dyes can be added directly to the solution or impregnated onto paper which may be dipped into the solution.

    Appendix: pH Theory XL15, 20, 25, 50 and 60 meters pH Electrodes The electrode system consists of two half cells: a pH indicating electrode, which is primarily responsive to the acidity (the hydronium ion concentration-tion) of a solution, and a reference electrode, which provides a constant voltage and completes the electrical circuit.

    Appendix: ISE Theory XL25, 50 and 60 meters Ion selective electrodes (ISE) respond to ionic activity or concentration in a liquid because of the characteristics of the electrode’s sensing membrane. Ideally, the ISE develops an electrical potential which is proportional to the activity or concentration of the ion for which the membrane is selective.

    Appendix: ISE Theory XL25, 50 and 60 meters This form of the Nernst equation states that the electrode potential varies directly with the log of the concentration in straight line manner, and results are then expressed in the preferred concentration units. The slope of the line is equal to the value of: Slope = S = 2.3RT/nF The table below gives theoretical slope values at 25°C.

    Appendix: ISE Theory XL25, 50 and 60 meters Incremental Methods These procedures can reduce errors caused by temperature variations, complex matrices, and complexation. They are also useful for applications where only occasional samples are analyzed. Incremental methods include: Known Addition, Known Subtraction, Analyte Addition, and Analyte Subtraction.

    Appendix: ISE Theory XL25, 50 and 60 meters Analyte Addition and Analyte Subtraction In the Analyte methods, the initial millivolt reading is taken with the electrode immersed in the standard; then an aliquot of sample is added, and the final millivolt reading is taken. Sample concentration is calculated from the change in the millivolt readings.

    Appendix: DO Theory XL40 and 60 meters Meter Operation The XL40 and XL60 meter uses the polarographic method of determining dissolved oxygen concentration. A voltage is maintained across two electrodes (a gold cathode and a silver anode) and an electrolyte separated from the sample solution by an oxygen permeable membrane. Oxygen diffuses from the sample across the membrane where it is reduced at the cathode.

    Replatinization is a relatively quick procedure to perform, taking no more than 5 minutes. Although replatinization is not a long process, the replatinization solution is costly. If you are not certain that replatinization will improve the performance of your accumet conductivity probe, please call the technical support hotline at 1-888-358-4706.

    Appendix: Conductivity Theory XL20, 30, 50 and 60 meters The four-cell electrode Traditionally, conductivity measurements were made with a “two cell“ electrode. This electrode used two metallic sensors, and anode and a cathode to which ions migrated. Under the influence of DC current, the electrodes quickly became polarized.
