 "Analytical
chemistry is the study of the
separation,
identification, and
quantification
of the
chemical
components of natural and artificial
materials.
Qualitative analysis
gives an indication of the identity of the chemical
species in the sample and
quantitative analysis
determines the amount of one or more of these
components. The separation of components is often
performed prior to analysis.
Analytical methods
can be separated into classical and instrumental.
Classical methods (also known as
wet chemistry
methods) use separations such as
precipitation,
extraction,
and
distillation
and qualitative analysis by color, odor, or melting
point. Quantitative analysis is achieved by
measurement of weight or volume. Instrumental
methods use an apparatus to measure physical
quantities of the analyte such as
light
absorption,
fluorescence,
or
conductivity.
The separation of materials is accomplished using
chromatography
or
electrophoresis
methods.
Analytical chemistry is also focused on
improvements in
experimental design,
chemometrics,
and the creation of
new measurement tools to provide better chemical
information. Analytical chemistry has applications
in
forensics,
bioanalysis,
clinical
analysis,
environmental analysis,
and
materials analysis."
