4. AIM AND OBJECTIVES
Aim
 The aim of the SIWES programme is to provide an avenue for students in
Nigeria higher institutions to gain industrial skills and experience in their course
of study.
Objectives
 To expose students to potential employers
 Providing students with opportunities to apply their theoretical knowledge in
their real work situation.
Enabling students contact and adequately prepare students for future job placement.

5. SAMPLE PREPARATION
 Sample is defined as a representative portion of any geological material
e.g. soil, rock, stream sediment,water
 Sample preparation is the process of converting sample into suitable
form for analysis

11. APPLICATION OF ATOMIC ABSORPTION SPECTROMETER
(AAS ) IN GEOLOGY
Atomic absorption spectromer provides cost effective viable solution
for the analysis of trace amount of metal in the entire rang of
natural material such as geological material
(AAS ) in geology focus on the analysis metal, rock, sediment
