GETTING STARTED

3.1 Connectors 1. Review the layout and arrangement of the rear connector panel.
2. Connect the electrode arm to the base.
3. Connect the power cable to the connector cable to the rear connector panel power jack and to a power source.
To connect RS232, see Data Management on Section 15.2.
3.2 pH Electrodes & Ion Specific Electrodes (Ion Specific Electrode applicable for CyberScan pH5500 only) This meter allows you to use two types of pH electrodes: the conventional glass pH electrode and the field effect transistor (FET) pH electrode.
If both types of pH electrodes are connected, the meter will read the FET electrode.
1. Carefully remove the protective cover from the end of the electrode. Before first using your glass pH electrode, soak it 2-4 hours in an electrode storage solution, pH 4 buffer, or KCI solution.
2. Remove the shorting cap on BNC connector. Connect the combination pH electrode in to the BNC input connector.
If a combination electrode is not used, connect the indicating pH electrode into the BNC input connector. Plug the reference electrode into the reference pin jack. Also, install the ATC probe into the ATC jack. Note: Be sure to connect all probes to the appropriate channel connectors (for example: Input 1, Ref 1 and ATC1).
Option: Connect the optional FET electrode by plugging it into the FET jack on the back meter panel. Allow the FET electrode to warm up five minutes before use. Connect ion specific electrodes in the same manner as pH electrodes.
If both a conventional and a FET electrode are connected to the meter, do not put them in a solution together because you will get inaccurate measurements. Do not discard the BNC shorting cap.
3. Rinse and blot-dry (do not wipe) electrodes between each measurement. Rinse electrodes with distilled or deionized water, or a portion of the next solution to be measured.
Between measurements, store conventional pH electrodes storage solution, pH 4 buffer, or KCI solution. Always leave the filling hole of liquid filled combination electrodes open. Refill when the level of solution gets below the manufacturers recommended level.
Proper electrode care is fundamental to obtaining reliable pH measurements. Improper care of the electrode may cause the meter reading to drift, respond slowly, or produce erroneous readings. For this reason, the electrode should always be conditional and used in accordance with manufacturers instructions.

Direct Reading with Standards The direct reading method is the most common method of ion measurement. When using this method, you will use standards of known values to standardize the meter with ion standards. An ionic strength adjuster (ISA) is added to both the standards and the sample. 2 to 5 standards are used to standardize the meter. The standards should bracket the expected value of the sample. The Ion specific electrode is immersed in a stirring sample and the ion concentration is read directly from the meter. Direct Reading with Blank offset The blank method is a method commonly used for determination of ion concentration in a sample with a very low level of ions present. Because of background interference at low concentration levels, a blank is used and the value of the ion concentration in the blank is subtracted from the value of the measured sample. Known Addition Method The known addition method is an incremental method used for samples with a complex matrix. A standard with a known concentration of the ion species of interest is added to the sample. The difference in mV potential is then used to calculate the concentration of the ion of interest. Known Subtraction Method The known subtraction method is also an incremental method. The ion of interest in the sample is not identical to the ion in the standard solution. The standard of known ion concentration that is added to the sample quantitatively reacts in the sample with the ion of interest. This reaction removes a fixed amount of the ion of interest from the sample solution. The ion concentration is then calculated based upon the difference in the mV potential. Analate addition The analate addition method is a modification of the known addition method. In the Analate Addition method, the initial mV measurement is recorded in a standard solution. The ion in the standard solution is the ion of interest and is detected by the ion selective electrode in use. A sample containing the ion of interest is then added to the standard solution. The difference in the mV potential is then used in the calculation of the concentration of the ion of interest. This method is useful if the sample temperature is significantly different than that of the standard. When the small volume of hot sample is added to the larger volume, the temperature impact becomes negligible.

Regardless of the status of the Auto Read Mode, STABLE will be displayed as the meter recognizes the measurement as stable.
Stability criteria are more stringent at the slower setting. Therefore, if the highest precision is required, then a slow setting would be desired. The medium or slow setting is recommended for Ion work.
Best results are obtained when the standards and the samples are at the same temperature.
8.4 Select Electrode Type This screen allows you to select the type of electrode that is specific for your ion of interest. Your choice of electrode informs the meter which default slope to use in the calculations made for the electrode efficiency and sample concentration. Once you have selected an electrode, you will not be required to enter the default slope numerically. Note: The default slope value specific for the electrode that you choose is a theoretical slope value that is used in the calculations to determine the efficiency of your electrode. This slope value is not the slope value that is displayed in the data box of the measurement screen. You will still need to standardize the meter using ion standards to determine the actual efficiency of your electrode. To Select Electrode Type
1. Access the Select Electrode Type screen from the Ion Setup screen. The current units are displayed on the screen. 2. Use the arrow keys to highlight the desired units. 3. Touch enter to accept Electrode Type and return to the Ion Setup screen. OR Touch exit to return to the ion setup screen, without making any changes
To Set Isopotential point The Isopotential point is the millivolts reading for an electrode at which temperature has no effect on the measurement. Ion selective electrodes, unlike pH electrodes, are not designed to achieve any particular isopotential point. If samples and standards are at different temperatures when performing ISE experiments, it will be necessary to experimentally determine the isopotential point of your own Ion Specific Electrode. The Ion Isopotential Point is set the same way as previously described in pH setup. See page 55 for instructions. To Set Alarm Limits This option allows you to set alarm limits for the Ion measuring mode. If the ion concentration measurement is outside the boundaries set by the minimum and maximum limits, an audible alarm and/ or a visual warning will appear to let you know that your sample measurement was outside of the set limits. The Ion Alarm Limits is set the same way as previously described in pH setup. See page 57 for instructions. To Set Print Criteria This screen allows you to select which criteria are printed with the measurement when you print the data or send it to the computer. The status of the current print criteria is displayed on the screen. The criteria option is active if ON appears to the right of the option. It is inactive if OFF appears to the right of the option. Any active criteria will be printed on demand. The Ion Print Criteria are set the same way as previously described in pH setup. See page 59 for instructions. To Set Print Interval You have three options for setting the print interval: manual printing, stable reading printing and timed interval printing. The Ion Print Interval is set the same way as previously described in pH setup. See page 61 for instructions. To Set Data Storage Criteria This screen allows you to select what criteria are stored in the meters memory with the measurement when you save the data. The status of the current data storage criteria is displayed on the screen. The criteria option is active if ON appears to the right on the screen. It is inactive if OFF appears to the right of the option. Any active criteria will be stored with the measurement. All storage criteria will be stored in the meters memory with the measurement. However, only active items will appear on the View Stored Data screens. Changing the status of the storage criteria to active from inactive will allow the criteria to be displayed with the previously stored data. The Ion Data Storage Criteria is set the same way as previously described in pH setup. See page 63 for instructions.

11.2 Incremental Methods

January 15, 2002 ID# Nh3 IM 00000 ATC slope mV
The incremental methods which include known addition, known subtraction, analate addition and analate subtraction and are particularly useful with samples containing complex ionic backgrounds which cannot be matched in standards. They are also useful with occasional samples whose temperatures vary. More information on these methods is available in the ISE Theory Section (See page 133). Standardizing the meter for all incremental methods Prior to conducting an analysis using any of the incremental methods, it is necessary to standardize the meter with at least two standards. This will establish a slope value for the electrode in use. The slope value is required in the incremental method calculations which yield the ion concentration of the sample. See ISE Theory page 133.
1. Touch std on the Ion measure screen to access the standardize screen. 2. Touch clear to delete the previous standardization from the memory of the meter. 3. Add ionic strength adjuster to the standards and the blank. 4. Immerse the ion selective electrode in the stirring standard. Always begin standardization with the least concentrated ion standard. 5. Touch std again to initiate the standardization process. 6. Use the keypad to enter value of the standard. 7. Touch enter on the keypad to accept the value. If you have entered a value in error, touch BS to clear the value and key in a new value. 8. Repeat steps 3-7 with additional standards.

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. In addition to the millivolts outputs of the electrode(s) in both the sample and the sample plus the standard, it is necessary to enter into the meter the volume of the sample, the volume of the standard, the volume of the Ionic Strength Adjuster (ISA) if used, the concentration of the standard and as previously stated the slope of the electrode in use. Your CyberScan research meter will prompt you through the method, permitting you to enter the appropriate parameters of the appropriate time. When the meter has all of the data needed for the calculation, it will display the ion concentration of the sample as well as the parameters entered for the calculation. The standard concentration should be high enough to nearly double the sample ion concentration after its addition. However, the standard volume should not significantly impact the sample volume. A 1:100 ratio of standard to sample ratio is optimal. For a monovalent electrode, the standard addition should results in a 15-30 mV change. For a divalent electrode, a 7-10 mV change is adequate. If the millivolts change is too high, the addition of the standard may affect the ionic strength and therefore the activity coefficients. This could result in inaccurate measurements. If the millivolts change is too small, readability errors are enhanced. See ISE Theory page 133.

CLEANING

The touch screen should be kept as clean as possible to preserve optical properties. Attempt to keep the screen free of dirt, dust fingerprints, etc. long term contact with abrasive materials will scratch the surface, and impair image quality. To clean, use a damp nonabrasive cloth towel and any commercially available window cleaner. The cleaning solution should be applied to the towel rather than the surface of the touch screen. The case is made out of durable ABS plastic. It can be cleaned with a damp cloth and a mild detergent. Do not use chemical solvents on the case.

13 TROUBLE SHOOTING

Your CyberScan meter contains many error messages to provide aid should trouble occur with a measurement or meter operation (touch pad and input errors). The messages are accompanied by a brief description of the error, and in some cases advice on how to correct it. An example of an error message is: Bad Electrode Slope The electrode you have standardized has a slope which is out of the normally acceptable range of 90% to 102%. You should try to restandardise, or replace your electrode if the problem persists. Note that you can continue to make measurements with this electrode; however, the readings may be inaccurate. Other error messages delivered by the meter are: Data Log full Data log empty Unrecognized date Unrecognized time Invalid pH limit Invalid ion limit Invalid limit Limit exceeded Channel 1 limit exceeded Channel 2 limit exceeded Invalid temperature Invalid Isopotential Invalid Print interval Invalid pH value Sample ID not found Operator ID not found Also, whenever possible, touch help for complete information about the meter operation in which you are currently engaged,

14 COMPLIANCE

Notice of Compliance Warning: this meter generates uses and can radiate radio frequency energy. If not installed and used properly, that is in strict accordance with the manufacturers instructions, it may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential are may cause interference, in which case the user, at his own expense, will be required to take whatever measures may be required to correct the interference. This product is to be used only as described in the manual. This product is for indoor use only, and must be used in a well ventilated area.

where E is the measured potential E* is the sum of the standard potential and all other constant potentials of the system R is the gas constant T is the temperature in K F is Faradays constant N is the valence of the ion being measured Activity, a, is not the same as concentration. It is a thermodynamic function whose value is influenced by the ionic environment in which the ion exists. Activity and concentration are the same in very dilute, ideal solutions. In non-ideal solutions, activity and concentration are related by an activity coefficient. ISEs sense the activity of free, uncomplexed ions rather than concentration. However, by calibrating the meter with standards with a similar ionic background as the sample, the difference between activity and concentration becomes negligible. Most often this is achieved by adding an ionic strength adjustor to both sample and standards. The Nernst equation becomes:

RT E = E* 2.3 nF (log c)

c is the concentration of the ion of interest.
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 25C
Species Slope (mV/ decade) +59.16 -59.16 Species Slope (mV/ decade) +29.58 -29.58
Monovalent cation Monovalent anion
Divalent cation Divalent anion
The Nernst equation thus reduces to: E = E* + S [log c] Ion-selective Analysis Methods Direct Analysis In this method, a sample concentration is determined by measuring the electrode potential and comparing to those obtained in standard solutions. Normally, an ionic strength adjustor and/ or pH adjustor must be added to both the samples and standards. This helps in that the closer the standard solution matrix is to the sample matrix, the more valid is the analysis. A number of standard solutions are used to standardize a pH/ mV/ ion meter, or to construct a calibration curve (by plotting the electrodes output in mV versus the log of the concentration). The sample concentration is then read from the meter or the calibration curve. The advantages of the direct method of analysis are: 1. Many samples (particularly those with relatively simple ionic backgrounds) can be quickly measured after a single calibration procedure. 2. The technique is valid over a wide range of concentrations. 3. Sample volume values are not required, and may also vary over a wide range.

Incremental Methods These procedures can reduce errors caused by temperature variations, complex matrices, and complexation. They are useful for applications where only occasional samples are analyzed. Incremental methods include: Known Addition, Known Subtraction, Analate Addition, and Analate Subtraction.
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. The techniques differ in that with Known Addition the standard added via the standard. For example, a chloride ISE can be immersed in sample for a chloride measurement. If a silver standard is added to the sample, AgCl precipitates, effectively removing or subtracting chloride ion from the sample. Equations for known addition and known subtraction calculations are as follow: Known Addition
Cstd Vstd (Vs+Vstd)10 E/S - V5

Known Subtraction

Cstd Vstd Vs- (Vs + Vstd)10
Cs is the concentration of the sample; Cstd is the concentration of the standard; Vs is the sample volume; Vstd is the standard volume; E is the difference in millivolt readings from the electrode; and S is the slope of the electrode determined in a previous standardization. Whereas the direct method is suitable for samples with fairly uncomplicated ionic matrices, the addition methods are advantageous with samples that have complex matrices, samples in which no ISA is added, samples in which excess complexing species are present, and samples whose concentration is in the non-linear region on the electrode response curve.
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. Analate Addition

Dual Channel Operation

GENERAL FEATURES

Channel Selection*
Choose to have 1 or 2 channels operating concurrently. Each channel operates independently. Standardization or calibration of one channel will not affect the other. A measurement on channel 1 does not reflect or influence the measurement on channel 2. The dual channel option allows the user to view the output of both channels on one screen at the same time.

HELP Screens

To guide you through the operation of the meter, the HELP key is always available. User prompts and context-specific HELP screens provide information in plain language. makes operating the meter a breeze. You might not even need the instruction manual!

You can customise the data you want to print. Simply select the desired information and tap print. Besides date, time, temperature and the measurement value, you can include the following information: last standardized values (and the date/time performed), electrode status, other related functions specific to measurement parameter (such as salinity and atmospheric values), meter model, serial number and operators name.

Data Storage

Similar to Print Criteria, memory data storage is highly customisable. Besides date, time, temperature and the measurement value, you can also choose to include in your print data the following information: last standardized values (and the date/time performed), electrode status, other related functions specific to measurement parameter (such as salinity and atmospheric values), meter model, serial number and operators name.

System Configuration

Simple yet powerful customisation in one meter. The system setup contains options not directly associated with measurement. These options, once set, will rarely be changed. Besides date and time, you can set beeper status; choose procedural level for different purposes; configure print data; input operators name (excellent for GLP procedure); set password to prevent unauthorised use of meter; check the meters information; or reset meter to factory default.

Measurement Setup

Each parameter setup is highly customisable. pH: buffer group, auto-read or auto-cal features, alarm limits, resolution, slope & offset, display configuration, and others. Conductivity: measurement units, cell constant, reference temperature, and temperature coefficient, 2 cell or 4 cell probes and others. Dissolved Oxygen: DO units, salinity value, measurement units for pressure, set-up for 5day BOD measurement, and other oxygenrelated measurement.

Display Configuration

Configure the information to be displayed on the huge display screen! Select one or two procedural levels to suit your preference: date/time information; sample identity; the last calibrated values (and the date/time performed); auto-cal or auto-read mode; electrode status; and others.
