Course Information

[3 days Course with hands-on] Code: AAS

INTRODUCTION / OBJECTIVES
This three-day course on elemental analysis, particularly on trace metals is designed for both chemists and non-chemists who are involving directly or indirectly in the use of atomic absorption and emission instrumentation. The course is brief but provides an overall review of the techniques from basic theory, instrumentation design to application. The course is most suitable for chemists and technicians who have no prior knowledge on the subject. The detail content of the course is as follows:

• The basic concept of atomic absorption and emission spectroscopy
  This will describe why and how atomic absorption and emission can be used as a tool for elemental analysis. And is aimed at providing basic understanding to the participants regarding the design of atomic absorption and emission instrumentation.

• Instrumentation design of atomic absorption (AAS) and emission (AES) spectrophotometer
  A detail discussion on the various instrumentation for the analysis of trace metals will be given. For AAS, the discussion will include the light source, sample atomization via flame technique, cold vapour and hydride generation methods for Hg and metalloid elements respectively and thermal method such as graphite furnace (GFAAS). For AES, the sample atomization technique will include flame and inductively coupled plasma (ICP-AES). Some aspects of the optics used in common and advanced AAS/AES instrumentation will be presented. Hyphenated technique such as ICP-MS (ICP mass spectrometer) will be described briefly.

• Application of atomic absorption and emission techniques to the analysis of trace elements
  This section will be devoted to various practical aspects in the analysis of trace elements such as metals and metalloids. Detail sample preparation methods (dry, wet and microwave sample digestions) will be discussed with examples from all kinds of sample matrices including water, biological and non-biological samples. Good laboratory practices to avoid contamination in ultra-trace analysis of metals and quality control in analytical procedures will be emphasized
