A new reference electrode for the 21st century. It is truly environmentally green; since it does not contain mercury. The Silver Sulfate Electrode (SSE) is non-hazardous and easy to dispose. The metal in use is pure silver and the electrolyte is potassium sulfate. The silver-silver sulfate electrode simplicity and fundamental ruggedness makes it a good candidate for many commercial applications where the electrochemical potential has to been measured or controlled.

Ag/Ag2S04 Reference Electrode potential:

+0.686 Volts vs. Normal Hydrogen Electrode (NHE)

+0.038 Volts vs. Mercury Sulfate Reference Electrode (MSE)

+0.440 Volts vs. Saturated Calomel Reference Electrode (SCE)

  • Use for chloride free investigations
  • Stable reference
  • Internal Filling: silver sulfate and saturated potassium sulfate
  • Easily disposable, contains no mercury
  • Replaceable frit

Electrode potential is stable to plus or minus one millivolt and recovers quickly from small temperature excursions. The Silver Sulfate Electrode will find applications in electro analysis, battery testing and maintenance, corrosion testing, electro-analytical studies and to measure half-cell potentials in lead-acid batteries. The electrodes are assembled using pure silver and then anodized to provide the stability and low noise characteristics required.

The junction is Electro-porous KT Glass serves as the ionicly conducting electrical pathway between the inside of the reference electrode and the bulk of your cell. The Electro-porous KT Glass frit is attached to the glass tube by 'heat shrinkable' Teflon sleeve. The KT Glass has a low electrical resistance and a modest drip rate. The electrical resistance of the reference electrode 'frit' is an important factor in determining the stability and speed of your potentiostat actual use. Remember, when changing KT Glass frits, the heat-shrink tubing should be trimmed flush with the end of the KT Glass frit to prevent the capturing of rogue air bubbles.

Details:

The (S.S.E.) use a saturated potassium sulfate solution with an excess of potassium sulfate crystals. These can sometimes be seen on the bottom of the electrode. The extra crystals dissolves into the electrolyte as the ions diffuse out through the liquid junction in normal use. This extra buffer of K2SO4 extends the time before the reference cell starts to drift due to the depletion of potassium ions in the electrolyte. Lead-acid batteries investigations and other possible uses of the silver silver sulfate reference electrode include: Determination of individual capacities of positive and negative plates, monitoring individual electrode behavior during deep discharge and cell reversal, optimization charge or discharge parameters, by controlling the current such that pre-determined limits of positive or negative half-cell potential are respected, observation of acid concentration differences, for example due to acid stratification, by measuring diffusion potentials (concentration-cell voltages) and detection of defective cells and defective plate sets, in a string of cells, at the end of their service life.
