Analytical chemistry

partition chromatography

Chemistry; Analytical 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 ...

designated volume

Chemistry; Analytical chemistry

The volume of an item of volumetric glassware as calibrated at a given temperature, frequently 20_C (68_F).

weight titration

Chemistry; Analytical chemistry

A titration in which the amount of titrant required is determined in terms of the weight that must be added to reach the end point.

partition coefficient

Chemistry; Analytical 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.

detection limit

Chemistry; Analytical chemistry

In chemical analysis, the minimum amount of a particular component that can be determined by a single measurement with a stated confidence level.

peak area

Chemistry; Analytical chemistry

The area enclosed between the peak and the base line on a spectrogram or chromatogram.

determination

Chemistry; Analytical chemistry

The finding of the value of a chemical or physical property of a compound, such as reaction-rate determination or specific-gravity determination.
