Analytical chemistry

Phase-solubility analysis

Chemistry; Analytical chemistry

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 ...

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 ...

Ultimate analysis

Chemistry; Analytical chemistry

The determination of the percentage of elements contained in a chemical substance.

Oxygen-flask method

Chemistry; Analytical 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 ...

Crosscurrent extraction

Chemistry; Analytical 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 ...

Ultrasensitive mass spectrometry

Chemistry; Analytical 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 ...
