    Electrodes Maintenance

    Electrode

    Visually inspect the electrode. If there are bubbles in the bottom of the electrode, spin the electrode around by holding • the cord. This will push the liquid into the lower part of the electrode rod. Control the crystal level in the electrode. If too high: liquid in the electrode should be emptied, the crystals rinsed with • distilled water and the electrode refilled with fresh KCl solution. If too low: fill with saturated KCl or fresh KCl crystals. Clean the electrode regularly with Renovo N (Renovo x if fat samples are measured).• To ensure accurate results avoid contact with the bottom of the cup during measurement.• Keep the electrode in pH 4 buffer overnight (not colored). Please note that this will lead to higher dissolving of the • crystals. Rinse electrode with distilled water between samples. If an electrode is stored in KCl (new electrode), it must be • soaked in buffer pH 4 for at least 2 hours before use. Check the electrode’s instructions as storage and activation recommendations may differ between electrodes.

    Conductivity Cell

    Clean platinum-coated conductivity cells gently, aggressive cleaning may lead to degradation of the platinum surface • layer. Rinse the cell with deionized water between sample measurements. If fat samples have been measured, the cell can • first be cleaned with solvents that dissolve the sample (for example ethanol and acetone). Finish by washing the cell with water. If deposits occur on the cell surface, it can be dipped in Renovo N (cleaning kit from Radiometer) for 1h and then be • cleaned with deionized water. For short-term storage, the cell can be stored in deionized water.• For long-term storage, the cell can be kept dry, or placed in deionized water. After long-term storage, the electrode • needs to be placed in deionized water for 8 hours before use. Do not touch the shiny surface of the platinum-coated cells.• To clean the platinum cells, dip the cell in deionized water several times. Do not rinse it with excessive water pressure. • The pressure may lead to a part of the platinum layer being rinsed off, this will affect the cell-constant and lead to incorrect measurement results.

    Radiometer Analytical’s unique Red Rod Technology provides not only fast response time but also long-term accuracy and reproducibility.

    Red Rod Electrodes Radiometer Analytical - Hach Lange

    Features:

    Reproducible measuring conditions ensured by the special bayonet head. The electrode fits into place in one easy movement and is fixed safely and securely in the same position for every measurement.

    Wide temperature range (0 to 100°C) thanks to fast temperature response of Red Rod Technology.

    Trouble-free liquid junction as Red Rod encapsulation of reference elements means no silver ions and therefore less risk of clogging.

    Fast and accurate response thanks to the symmetrical electrode chain formed by the internal and external Red Rod reference elements.

    Stable signal as the Red Rod Technology protects the reference elements from light interference. Saturated KCI salt-bridge aids stable liquid junction potential.

    The symmetry of Red Rod electrodes means that the iso pH is the same as the zero pH which provides highly reproducible results even when temperature fluctuations occur. The figure compares the measurements performed with a general-purpose Red Rod electrode and a traditional combined electrode. A MeterLab setup was used to measure certified standard pH solutions, pH 7.000 thermostated at 50°C and pH 4.005 thermostated at 25°C. The figure shows the fast response of the Red Rod electrode to changes in pH and temperature (curves offset to increase readability).

    The Right Electrode for your Application

    Combined pH electrodes

    ELECTRODES

    There is a Radiometer Analytical electrode for every application. The above table gives examples of the many applications for which Radiometer Analytical electrodes can be used. Where possible, choose an electrode which is “Recommended” but where one electrode is required for several applications, it may be

    necessary to select one which is “Acceptable”. Full specifications of the electrodes featured in the table are given on the following pages. In addition to your application, there are other considerations when choosing an electrode. The length and diameter obviously depend on the sample size and

    When measuring at high temperatures, the electrochemical system within the electrode needs to be considered. Radiometer Analytical offers Ag/AgCl electrodes specially designed for high temperature measurements. To avoid chloride interference, a reference

    ELECTRODES

    electrode with a chloride-free reference system must be used (e.g. Hg/Hg2SO4 with K2SO4 salt-bridge) or a reference electrode with a double salt-bridge construction.

    pH glass electrodes from Radiometer Analytical are made with highly shock-resistant glass, making them extremely tough. The average lifetime of a correctly maintained glass pH electrode is approximately 2 years. Certain electrodes are made with special glass for pH measurements in strongly alkaline solutions. These electrodes allow measurements within the 0 - 14 pH range without significant deviation from the theoretical response. Glass pH electrodes are always used in combination with reference electrodes. The zero pH of Red Rod glass pH electrodes when used with their recommended reference electrode is approximately pH 6.65. The zero pH of glass pH electrodes is approximately pH 6.65 when measured against a calomel reference electrode (e.g. REF421, XR110) and approximately pH 7.25 when measured against an Ag/AgCl reference electrode (e.g. REF321).

    During measurement, the salt-bridge junction (also called liquid junction protection tube) prevents the reference electrode from being contaminated by the media and vice-versa. It consists of a glass tube terminated by a liquid junction. Always ensure the filling solution used corresponds to the application.

    A reference electrode provides a stable potential whatever the measurement conditions. The main differences between reference electrodes are the type of reference system and the liquid junction. Radiometer Analytical offers electrodes using both Red Rod and traditional technology. Electrodes with a double junction are mostly designed for measurements using ion-selective electrodes or samples sensitive to Cl- or K+. Sleeve junctions have a high flow to prevent the risk of clogging. Porous pins are used for general applications. Fibre reference electrodes have a slow flow to avoid contamination of the media.

    Conductivity measurement is temperature dependent (if the • temperature increases so does the conductivity value). When performing conductivity measurements, it is advisable to choose a cell with a built-in temperature sensor or use a separate sensor.

    Remember to calibrate your conductivity • cell regularly as the cell constant may vary due to changes in electrode surface due to contamination, for example.

    Maintenance solutions

    Filling and storage solutions for combined and reference electrodes

    The maintenance requirements of electrodes vary according to the application. After measurements in aqueous solutions, cleaning with a mild solution such as RENOVO•N is sufficient. However, when the solutions contain protein, for example, stronger cleaning agents such as RENOVO•X or Pepsin in HCl are required. For junctions contaminated with sulphides or AgCl precipitate, Radiometer Analytical’s Thiourea Solution is ideal. The operating instructions provide cleaning instructions for each type of electrode.
