Analytical chemistry

redox titration

Chemistry; Analytical chemistry

A titration characterized by the transfer of electrons from one substance to another (from the reductant to the oxidant) with the end point determined colorimetrically or potentiometrically.

fluorometric analysis

Chemistry; Analytical chemistry

A method of chemical analysis in which a sample, exposed to radiation of one wavelength, absorbs this radiation and reemits radiation of the same or longer wavelength in about 10_ 9 second; the ...

bulk sampling

Chemistry; Analytical chemistry

The taking of samples in arbitrary, irregular units rather than discrete units of uniform size for chemical analysis.

reduction

Chemistry; Analytical chemistry

Preparation of one or more subsamples from a sample of material that is to be analyzed chemically.

fractional precipitation

Chemistry; Analytical chemistry

Method for separating elements or compounds with similar solubilities by a series of analytical precipitations, each one improving the purity of the desired element.

calibrant

Chemistry; Analytical chemistry

In chemical analysis, a substance used to calibrate the response of a measurement system to the analyte.

reference material

Chemistry; Analytical chemistry

A material or substance whose properties are sufficiently well established to be used in calibrating an apparatus, assessing a measurement method, or assigning values to other materials.
