Basic electrochemical technique for quantitative analysis of conducting solutions containing oxidizable or reducible material; measurement is based on the weight of material plated out onto the electrode.
Industry:Chemistry
A volumetric analysis that employs precipitation of insoluble silver salts; the salts may be chromates or chlorides.
Industry:Chemistry
Solution titration in which the end point is read from the electrode-potential variations with the concentrations of potentialdetermining ions, following the Nernst concept. Also known as constant-current titration.
Industry:Chemistry
A process used to separate isotopes or ionic species by the differences in their ionic mobilities in an electric field.
Industry:Chemistry
A technique for the analysis of mixtures of two or more compounds in which the mobile phase (sample and carrier) rises through the fixed phase.
Industry:Chemistry
In a titration, a substance that precipitates from solution in a clearly visible form at the end point.
Industry:Chemistry
Extremely sensitive gas chromatography detector that is a modification of the argon ionization detector, with conditions adjusted to favor the formation of negative ions.
Industry:Chemistry
An analytical process in which the chemical material being analyzed is oven-heated to leave only noncombustible ash.
Industry:Chemistry
The number of milliliters of asphaltic precipitate formed when 10 milliliters of petroleum-lubricating oil is mixed with 90 milliliters of a special-quality petroleum naphtha, then centrifuged according to American Society for Testing and Materials test conditions; used to determine the quantity of asphalt in petroleum-lubricating oil.
Industry:Chemistry
An analytical technique that uses a narrow electron beam, usually with a diameter less than 1 millimeter, focused on a solid specimen to excite an x-ray spectrum that provides qualitative and quantitative information characteristic of the elements in the sample. Abbreviated EPXMA.
