Among the various possibilities that offer the EC detection, ampe-rometry and conductimetry are, in this order, the most common. Although potentiometry results are a very interesting technique in many fields of Analytical Chemistry, it has not found enough echo in the microchip technology. Its incursion in microchips is related with the employment of ion-selective electrodes for Ba2+ determination [55] or potentiometric titration of iron ferrocyanide [56], but it has not yet been associated with CE microchips. 

Prussian blue. The most common and best-known name for blue iron ferrocyanide (iron blue) pigments made by a variety of procedures. 

Fe [Fe(Cn)g]3 Iron ferrocyanide, more commonly known as Prussian Blue, is a famous compound with a brilliant greenish-blue color. It inspired chemists to understand the mechanisms by which atoms produce color. To artists, it serves as a pigment and still today is readily available. It s also known as Chinese blue and milori blue.

Neubeig Blue. A pigment comprising copper carbonate, and iron ferrocyanide and sulphate. 

Prussian Blue. An iron-ferrocyanide blue pigment. 

The zinc may be detected by dissolving a small amount of the test material in dilute sulfuric acid followed by the addition of 2 % solution of potassium ferrocyanide white Zn2[Fe(CN)e] precipitates. However, if iron salts are present in the sample, the colorless zinc salt is tinted blue because of the concurrent production of iron ferrocyanide. Under such circumstances the blue product is treated with ammonia water and the suspension is filtered or centrifuged. The clear solution is acidified a white precipitate results. 

By a similar method Lottermoser was able to prepare hydrosols of silver ferro and ferricyanide, phosphate, and arsenate. In these instances it was found easier to prepare hydrosols by allowing silver nitrate to flow into the solution of the alkali salt in question than it was by the reverse process. These solutions differ in this respect from the hydrosols of silver halides. Similar conditions hold for the preparation of the hydrosols of copper or iron ferrocyanides.
