Introduction to Analytical Chemistry
• Analytical Chemistry is the branch of chemistry that
deals with the separation, identification, and
quantification of chemical composition of substances
( or chemical components of a sample).
• Employs chemical principles and analytical methods
to separate, identify and quantify the chemical
components of samples.
Analytical Chemistry
•is concerned with the questions of "what
chemicals are present, what are their
characteristics and in what quantities are
they present in any substance/material?“
• The process of determination or
identification is called chemical
analysis.
Classification of Chemical Analysis
•Qualitative analysis
• determination of chemical identity of species in the
sample.
e.g. identity the elements, ions and compound in
the sample.
•Quantitative analysis
•determination of the amount of species or analytes,
in numerical terms (determining the quantity of the
analyte present)
•Analyte = species of interest to be determined
Analytical Chemistry is classified into two general areas of
chemical analysis
Focus in this course is quantitative methods of analysis
Separation of components/chemical species is often
performed prior to analysis (by physical or chemical
‘conditioning’)
Structural analysis – involves determining spatial
arrangement of atoms in a molecule or crystalline
compound or confirmation of the presence or position of
certain organic functional groups (Qualitative)
Roles of Analytical Chemistry in
Sciences & Our Everyday Life
