Apera Instruments, LLC-AI1312 Apera Instruments 201T-S pH/Temp. Electrode, 8-pin Connector, The Replacement Electrode for Apera 400/400S Series Portable Meters

  • 3.Glassy carbon electrode is one of the widely used working electrodes. It is a good inert electrode with good conductivity, high hardness, high finish, high hydrogen overpotential, wide polarization range and chemical stability. It can be used as inert electrode for anodic stripping, voltammetric determination of cathode and variable valence ions, and can also be used as chemically modified electrode.
  • 4.The glassy carbon surface must be mirror and clean. Since the surface of glassy carbon is easily polluted by some organic metal compounds, which seriously affects the measurement (no peak, no impurity peak and no recurrence), it must be cleaned before measurement.
  • 5.There are three main maintenance methods, chemical method 1. Nitric acid immersion and scrubbing. 2. Soak and scrub with ammonia water, anhydrous ethanol or acetate 1:1. 3. It can also be scrubbed with alcohol and then soaked in 6nhcl or 4nho3. Electrochemical treatment: repeated polarization (reset scan) (anode cathode to cathode) in the voltage range of + 0.8V - (- 1.8V (0.5mkclph7 except o2i).
