Quantitative analysis

from Wikipedia, the free encyclopedia

A quantitative analysis is a chemical and / or physical process that aims to answer the question of how much of a substance is present in a given sample. In qualitative analysis . on the other hand, it is examined which substances are present in the sample.

All methods can be divided into the “classic” and the physical analysis methods.

Classic methods

The classical methods are about chemical conversions, after which a mass, amount of substance and volume is determined. The masses of the individual elements can then be determined using stoichiometric conversion factors. Because of the measurement types, there are therefore the following sub-categories:

Physical methods

The physical methods are about the measurement of concentration-dependent physical properties from which a concentration or mass can be calculated.

  • Electroanalytical methods:
    • Conductometry (measurement of the conductivity of an electrolyte solution)

Physico-chemical methods

Methods in which both chemical reactions and physical processes play a role include:
