Solvent technique used to determine the amount and number of components in a solid substance; the weight of sample added to the solvent is plotted against the weight of sample dissolved, with breakpoints in the curve occurring with each progressive saturation of the solvent with respect to each of the components; can be combined with extraction and recrystallization procedures.
Industry:Chemistry
Analysis of difficult-to-separate materials in solution by diffusion effects, using, for example, dialysis, electrodialysis, interferometry, amperometric titration, polarography, or voltammetry.
Industry:Chemistry
The determination of degree of unsaturation of organic compounds by reacting with sulfuric acid and measuring the heat of reaction.
Industry:Chemistry
Analysis of a binary mixture of miscible liquids by titrating with a third liquid that is miscible with only one of the components, using the ternary phase diagram to determine the end point.
Industry:Chemistry
A device for comparing standard and sample colors by means of rotating color disks.
Industry:Chemistry
An acid solution of known concentration used to determine the basicity of another solution by titration.
Industry:Chemistry
Variation of column-development or elution chromatography in which the solvent is sorbed more strongly than the sample components; the freed sample migrates down the column, pushed by the solvent.
Industry:Chemistry
An apparatus or a standard solution used to determine the amount of acid in a sample.
Industry:Chemistry
Number scale for comparison of antiseptics, using the efficacy of phenol as unity.
