Reaction equilibrium constant for the reaction forming soluble complexes during compleximetric titration.
Industry:Chemistry
A determination of the amount of an electrolyte released during electrolysis by measuring the number of coulombs used.
Industry:Chemistry
A paper chromatography technique in which the sample is resolved by standard procedures (ascending, descending, or horizontal solvent movement) and then turned at right angles in a second solvent and re-resolved.
Industry:Chemistry
A compound whose color in the oxidized state differs from that in the reduced state.
Industry:Chemistry
An extraction process involving the introduction of a sample, all at once, into a continuously flowing countercurrent system where both phases are moving in opposite directions and are continuously at equilibrium.
Industry:Chemistry
The determination of the percentage of elements contained in a chemical substance.
Industry:Chemistry
Technique to determine the presence of combustible elements; the sample is burned with oxygen in a closed flask, and combustion products are absorbed in water of dilute alkali with subsequent analysis of the solution.
Industry:Chemistry
Procedure of batchwise liquid-liquid extraction in a separatory funnel; solvent is added to the sample in the funnel, which is then shaken, and the extract phase is allowed to coalesce, then is drawn off.
Industry:Chemistry
A form of mass spectrometry in which the ions to be detected are accelerated to megaelectronvolt energies in a particle accelerator and passed through a thin gas cell or foil, stripping away outer electrons, so that contaminating molecules dissociate into lower-mass fragments, and isobars can be distinguished by particle detectors that measure ionization rate and total energy.
