Instruction Manual CyberScan PC5500/ 5000 Measuring Ion Concentration in Samples Using the Incremental Methods When performing known addition, you will add an aliquot of standard solution containing the ionic species of interest to a known volume of your sample. The mV readings of the sample can then be calculated based upon the difference in the mV readings. The use of the incremental methods requires that certain parameters be identified.
Instruction Manual CyberScan PC5500/ 5000 To take a measurement 1. Immerse the ion selective electrode in a known volume of the sample solution. 2. Stir the sample. 3. Touch KA to take the first mV reading of sample. Wait for the reading to stabilize (STABLE will appear). OR Touch KA to accept the current reading. 4. Add a known volume of standard solution to the sample. 5. Touch KA to take the second mV reading of sample. Wait for the reading to stabilize (STABLE will appear).
Instruction Manual CyberScan PC5500/ 5000 12.4 Known Subtraction Method The procedure for known subtraction is very similar to that for known addition method. An aliquot of standard is added to a known volume of the sample. The difference is that the standard does not contain the same ionic species that you are trying to measure in the sample. Instead, it contains an ion that will complex or precipitate the ion of interest, removing it from the sample.
Instruction Manual CyberScan PC5500/ 5000 10. Use the keypad to enter the concentration of the standard solution added to the sample. 11. Touch enter to accept the value. 12.

Touch print to send the data to memory if sample ID# has been assigned or to print the data on the screen.
Instruction Manual CyberScan PC5500/ 5000 12.6 Analate Subtraction The analate subtraction method is useful when no ion specific electrode is available to measure the ion of interest directly. Like known subtraction the sample and the standard contain different ionic species. However, the ion being measured is in the standard and not in the sample. The reduction of free ions in the standard solution is proportional to the concentration of the ion of interest in the sample. See ISE theory page 160.

Instruction Manual CyberScan PC5500/ 5000 17.4 pH Theory Since its introduction by the Danish Chemist Sorensen in 1909, pH measurement has become one of the most commonly used and important measurements in both laboratory and industry settings. pH measurement and control is vital to a wide array of endeavors including municipal and industrial wastewater treatment, and textile, pharmaceutical, food and pH. Most organisms can exit only within a narrow pH range.
Instruction Manual CyberScan PC5500/ 5000 At 25 °C in pure water, the concentration of hydronium ions is extremely small, 1 X 10-7 Moles/liter, and balanced by an equal concentration of hydroxyl ions.
Instruction Manual CyberScan PC5500/ 5000 pH Measurement The pH value of a sample can be determined in several ways. These include the use of organic dyes which change colour in certain pH ranges. The dyes can be added directly to the solution or impregnated onto paper which may be dipped into the solution. At best, these “colorimetric” methods yield approximate pH values, often with an accuracy of plus or minus 0.5 pH units.

Instruction Manual CyberScan PC5500/ 5000 Reference electrodes typically consist of three elements: an internal reference electrode, a filling solution, and a reference junction through which the filling solution can “flow”, and provide electrical contact with the sample and the internal reference electrode. The most convenient internal reference electrodes are made from a metal (such as silver or mercury) and its sparingly soluble salt (silver chloride or mercurous chloride).
Instruction Manual CyberScan PC5500/ 5000 17.5 ISE Theory 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 which the membrane is selective. For example, the fluoride electrode can be used to directly sense fluoride ion in drinking water.
Instruction Manual CyberScan PC5500/ 5000 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 Species Slope (mV/ decade) Monovalent cation Monovalent anion Species +59.16 -59.
Instruction Manual CyberScan PC5500/ 5000 Known addition and Known Subtraction With the Known Addition and Known Subtraction methods, the initial millivolts output of the electrode in the sample solution is measured. Then an aliquot of standard solution is added, and a final millivolts potential is measured. The concentration of the sample can then be computed from the observed change in the millivolts readings before and after the addition.
Instruction Manual CyberScan PC5500/ 5000 Analate Addition and Analate Subtraction In the Analate 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.
Instruction Manual CyberScan PC5500/ 5000 17.6 Conductivity Theory Conductance is a quantity associated with the ability o primarily aqueous solutions to carry an electrical current, I, between two metallic electrodes when a voltage E is connected to them. Though water itself is a rather poor conductor of electricity, the presence of ions in the water increases its conductance considerably, the current bring carried by the migration of the dissolved ions.
Instruction Manual CyberScan PC5500/ 5000 Thus comes the term specific conductance or conductivity. The relationship between conductance and specific conductivity is: Specific Conductivity, S.C.
Instruction Manual CyberScan PC5500/ 5000 Conductivity Measurement Conductivity electrodes consist of glass or epoxy bodies in which platinum or platinised sensing elements and are designated two-cell electrode has two such sensing elements and are designated two-cell electrodes. The previous discussion has focused on this type of electrode. Four cell electrodes are also available, and the theory and application of these are in a separate section.
Instruction Manual CyberScan PC5500/ 5000 The four-cell electrode Traditionally, conductivity measurements were made with a “two cell” electrode. This electrode used two metallic sensors, an anode and a cathode to which ions migrated. Under the influence of DC current the electrodes quickly became polarized. In this situation, molecules formed at the electrode surfaces and ions migrating to the area collect around the respective anode or cathode and actually screen it from other ions.
Instruction Manual CyberScan PC5500/ 5000 Since temperature effects the conductivity measurement so profoundly, the usual practice is to reference the conductivity to some standard temperature. This is typically 25°C but the PC 5000 also permits the choice at 15°C and 20°C in the Select Temperature Coefficient.
