  2. Polarography - Wikipedia

    en.wikipedia.org/wiki/Polarography

    Heyrovský's Polarograph. Polarography is an electrochemical voltammetric technique that employs (dropping or static) mercury drop as a working electrode. In its most simple form polarography can be used to determine concentrations of electroactive species in liquids by measuring their mass-transport limiting currents.

  3. Voltammetry - Wikipedia

    en.wikipedia.org/wiki/Voltammetry

    The reference is the most complex of the three electrodes; there are a variety of standards used. For non-aqueous work, IUPAC recommends the use of the ferrocene/ferrocenium couple as an internal standard. [8] In most voltammetry experiments, a bulk electrolyte (also known as a supporting electrolyte) is used to minimize solution resistance. It ...

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction. One form of electro-galvanic fuel cell based on the oxidation of lead is commonly used to measure the concentration of oxygen gas in underwater diving and medical breathing gases .

    The sensors only begin to work effectively when heated to approximately 316 °C (600 °F), so most newer lambda probes have heating elements encased in the ceramic that bring the ceramic tip up to temperature quickly. Older probes, without heating elements, would eventually be heated by the exhaust, but there is a time lag between when the ...

    The barriers prevent (glass membrane), or slow down (ceramic junction), the mixing of the different solutions. In this schematic representation of the galvanic cell, one will note the symmetry between the left and the right members as seen from the center of the row occupied by the "Test Solution" (the solution whose pH must be measured).

  9. Galvanic isolation - Wikipedia

    en.wikipedia.org/wiki/Galvanic_isolation

    Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no direct conduction path is permitted. [ 1 ] [ 2 ] Energy or information can still be exchanged between the sections by other means, such as capacitive , inductive , radiative , optical , acoustic , or mechanical coupling.
