The volume of an item of volumetric glassware as calibrated at a given temperature, frequently 20_C (68_F).
Industry: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.
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 area enclosed between the peak and the base line on a spectrogram or chromatogram.
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 thermochemical analytical procedure applicable to biochemical and chemical analyses; the salient feature is rapid mixing of a reagent stream with an isothermal solvent stream into which discrete samples are intermittently injected; peak enthalpograms result which exhibit the response characteristics of genuine differential detectors.
Industry:Chemistry
In the separation of mixtures by paper chromatography or thin-layer chromatography, the production of colored derivatives of the solutes by spraying the stationary phase with selective reagents in order to establish the location of individual substances.
Industry:Chemistry
A method of chemical analysis that bases characterization completely on standards defined in terms of physical properties.
