Analytical chemistry is the science of measurement and identification of the chemical compounds that underlie most aspects of modern life and plays a central part within the chemical industry. It also involves the processing and communication of information about the composition and structure of matter.
In addition to the traditional chemistry areas, the course covers research methods, chemical separation and instrumentation and statistics and chemometrics.
Postgraduate students in analytical chemistry will acquire skills that will enable them develop new methods for use of instruments in the analysis of chemical compounds.
Graduates of analytical chemistry can find employment in government departments, parastatals, quality control laboratories, research and development, production, pharmaceutical industry, water purification industry, wastewater management industry, forensic science, process design and product development, instrumental design industry, cement industry, tanning industry, fertilizer industry, plastics industry, consumer industry, textile industry, dyes and paints industry, , glass industry, pulp and paper industry just to name a few.
