2. PRESENTATION OUTLINES Introduction Sample preparation laboratory Atomic absorption spectrometer (AAS) Equipment used in ( AAS) laboratory Application of( AAS) in geology

3. BRIEF HISTORY OF THE ORGANISATION NGRL one of the centers of excellence established by the NGSA. To conduct analytical test on rock and mineral. Geochemical analysis of rocks, minerals, water sewage and soil sample Mineral separation and dressing as well as rock crushing Preparation of thin section, polished rock and mineral sample

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 M ethod of sample preparation Chemical method Physical method
