Names ions

The name ion comes from the Greek word for go, because charged particles go cither toward or away from a charged electrode. 

U 1 Name ions, binary inorganic compounds, oxoacids, compounds with common polyatomic ions, and hydrates, and write their formulas (Toolboxes D.l and D.2, Self-Test D.l, and Examples D.l, D.2, and D.3). 

The EXAFS signal from the Co K edge gives information on the surroundings of cobalt. As an active sulfided Co-Mo/AI2O3 catalyst contains at least two cobalt species, namely ions inside the A1203 lattice and in the Co-Mo-S phase, it is better to investigate the Co-Mo-S phase in carbon-supported catalysts. The latter can be... 

The original name ion-pair chromatography has been criticized on the basis that either no ion-pair formation occurs under conditions used in... 

The name "ion-exchange membrane mainly refers to the fact that this ion-selective property can best be realized by using materials closely resembling the ion-exchange resins. 

Order of Naming Ions If the compound is ionic, the name of cation is mentioned first followed by the name of onion. For example,... 

At the opposite extreme of molecular size from DNA, small molecules and free atoms can be ionized and subjected to electrophoresis in the gas phase. The technique, named ion mobility spectroscopy (IMS) or plasma chromatography, would better be called gaseous electrophoresis for consistency. The uses and theory of this method can be found in the literature [31,32]. 

The name ion exchange aptly describes the process used chromatograph-ically to separate ions and some polar molecules. Because ion formation is favored in aqueous solutions, the mobile phase in IEC is aqueous, usually buffered to a particular pH. Ionic exchange sites are immobilized on the stationary phase, represented in the following equation as R . 

Cation — A positively charged ion. A cation has fewer electrons than protons and is attracted by a negatively charged - electrode. The name ion was created by - Faraday, from Greek i 6/y, neutral present participle of ieuai, to go , so cation, tc anon, means (a thing) going down . 

This simple exercise demonstrates the chromatographic separation of the components of a mixture by a procedure that relies on two of the principles discussed above, namely ion-exchange chromatography and size-exclusion chromatography. The components to be separated (see Table 2-3) differ greatly from one another both in their molecular... 

G.C. STAFFORD, PE. KELLY, J.E. SYKA, W.E. REYNOLDS and J.F.J. TODD describe the development of a gas chromatography detector based on an ion trap and commercialized by Finnigan under the name Ion Trap [54],...
