TEXT A
ANALYTICAL CHEMISTRY
Analytical chemistry is the analysis of material samples to gain an understanding of
their chemical composition and structure. It has wide range of application from routine quality
control in industrial settings to cutting edge of chemical research in developing new
compounds. Monitoring pollution in the environment, development of new materials, drug
manufacture, and even forensic science all make use of techniques and methods developed in
analytical chemistry.
Analytical chemistry can
be split into two main types, qualitative and quantitative:
a) Qualitative inorganic analysis seeks to establish
the presence of a given
element or inorganic compound in a sample.
b) Qualitative organic analysis seeks to establish the presence of a given
functional group or organic compound in a sample.
c) Quantitative analysis seeks to establish the amount of a given element or
compound in a sample.
Most modern
analytical chemistry is
quantitative. Quantitative analysis can be further split
into different areas of study. The material can be
analyzed for the amount of an element or for the
amount of an element in a specific chemical species.
The latter is of particular interest in biological
systems; the molecules
of life contain carbon,
hydrogen, oxygen, nitrogen, and others, in many
complex structures.
There is a bewildering
array of techniques
available to separate, detect and measure chemical compounds.
