At the end of the second semester, the candidates are required to present their research and
findings in a written report and defend them in the Viva Voce session. The presentations would then
be assessed by the supervisor and examiner appointed by the department.

SQC7003 Atomic Spectroscopic Analysis

The module is designed to introduce the general aspects on atomic spectroscopy, flame and plasma
atomic emission spectrometry (AES), atomic absorption spectrophotometry (AAS), including non-
flame AAS and hydride-generation technique, atomic fluorescence spectrometry (AFS), molecular
fluorescence spectrometry (MFS) and inductively coupled plasma (ICP). Atomic absorption
spectroscopy (AAS) is a spectro-analytical procedure for the quantitative determination of chemical
elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic
emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted
from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an
element in a sample. The wavelength of the atomic spectral line gives the identity of the element
while the intensity of the emitted light is proportional to the number of atoms of the element.
Fluorescence spectroscopy (also known as fluorometry or spectrofluorometry) is a type of
electromagnetic spectroscopy which analyzes fluorescence from a sample. It involves using a beam
of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and
causes them to emit light; typically, but not necessarily, visible light. An inductively coupled plasma
(ICP) is a type of plasma source in which the energy is supplied by electric currents which are
produced by electromagnetic induction, that is, by time-varying magnetic fields. Topics to be
discussed in this module will include spectro-chemical information such as spectro-chemical
measurements, optical components of spectrometers, optical sources, transducers and
measurement systems, signal-to-noise ratio considerations and methodology in spectro-chemical
analysis.
