Qualitative or quantitative determination of the components of a material, as an ore or a drug.
Industry:Chemistry
Amperometric titration in which the potential of a suitable indicator electrode is measured during the titration.
Industry:Chemistry
A form of flame photometry in which a sample solution to be analyzed is aspirated into a hydrogen-oxygen or acetyleneoxygen flame; the line emission spectrum is formed, and the line or band of interest is isolated with a monochromator and its intensity measured photoelectrically.
Industry:Chemistry
In flame spectrometry, conversion of a volatilized sample into free atoms.
Industry:Chemistry
A branch of analytical chemistry concerned with quantitative and qualitative information about a chemical process.
Industry:Chemistry
That stage in the titration at which an effect, such as a color change, occurs, indicating that a desired point in the titration has been reached.
Industry:Chemistry
An atom-counting method in which individual atoms of a chosen isotope are captured and detected with a laser trap.
Industry:Chemistry
A method of elemental analysis in which the energy of the characteristic x-rays emitted when a sample is bombarded with a beam of energetic protons is used to identify the elements present in the sample.
Industry:Chemistry
Generic designation for a group of modern thermochemical methodologies such as thermometric enthalpy titrations which rely on monitoring the temperature changes produced in adiabatic calorimeters by heats of reaction occurring in solution; in contradistinction, classical methods of thermoanalysis such as thermogravimetry focus primarily on changes occurring in solid samples in response to externally imposed programmed alterations in temperature.
Industry:Chemistry
1. Titration with quantitative reaction and measured flow of reactant. 2. Electrically generated reactant with potentiometric, ampherometric, or colorimetric end-point or null-point determination.
