Polarography technique in which the rate of change of current with respect to applied potential is measured as a function of the applied potential (di/dE versus E, where i is current and E is applied potential).
Industry:Chemistry
A method of trace analysis in which a beam of ions is directed at a thin foil on which the sample to be analyzed has been deposited, and the energy spectrum of the resulting x-rays is measured.
Industry:Chemistry
1. In the purification of a laboratory sample, the cleaning of residual liquid impurities from precipitates by adding washing solution to the precipitates, mixing, then decanting, and repeating the operation as often as needed. 2. The removal of soluble components from a mixture of solids by using the effect of differential solubility.
Industry:Chemistry
Factor in light-scattering equations used to compensate for the loss in scattered light intensity caused by destructive interference during the analysis of macromolecular compounds.
Industry:Chemistry
Chromatographic procedure in which the stationary phase is a high-boiling liquid spread as a thin film on an inert support, and the mobile phase is a vaporous mixture of the components to be separated in an inert carrier gas.
Industry:Chemistry
In the equilibrium distribution of a solute between two liquid phases, the constant ratio of the solute’s concentration in the upper phase to its concentration in the lower phase. Symbolized K.
Industry:Chemistry
In chemical analysis, the minimum amount of a particular component that can be determined by a single measurement with a stated confidence level.
Industry:Chemistry
The finding of the value of a chemical or physical property of a compound, such as reaction-rate determination or specific-gravity determination.
Industry:Chemistry
The smallest amount of an element or compound that is detectable in or on a given sample; expressed in terms of mass units or numbers of atoms or molecules.
Industry:Chemistry
A method of chemical analysis that bases characterization completely on standards defined in terms of physical properties.
