COURSE OVERVIEW:

The meaning of this course resides in the sophisticated application of Atomic Absorption Spectrometry for the ultra-trace detection of metallic elements across various industrial matrices. AAS remains a cornerstone of analytical chemistry due to its high specificity and sensitivity, yet mastery of the technique requires a deep understanding of atomization physics and spectral interferences. This program is designed to move operators from basic procedural execution to high-level analytical troubleshooting and method development.

The scope of the training encompasses the three primary modalities of the technique: Flame AAS, Graphite Furnace AAS, and Vapor Generation (Hydride and Cold Vapor) systems. It addresses the technical nuances of light source technology, including Hollow Cathode and Electrodeless Discharge lamps, and the critical role of background correction systems. Participants will explore the chemistry of matrix modification and the physics of atomization to achieve the highest possible precision in difficult samples like oils, brines, and ores.

The coverage includes comprehensive instruction on sample preparation techniques, from microwave-assisted acid digestion to dry ashing and fusion. Attendees will learn to optimize burner height, gas flow rates, and furnace temperature programs to maximize signal-to-noise ratios. By integrating quality control protocols and calibration strategies, the course ensures that participants can deliver traceable elemental data that meets the rigorous demands of environmental, pharmaceutical, and metallurgical industries.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Explain the quantum mechanical principles of atomic absorption and emission.
• Optimize Flame AAS parameters including gas stoichiometry and burner alignment.
• Develop complex temperature programs for Graphite Furnace atomization.
• Master the use of Hydride Generation for the detection of As, Se, and Hg.
• Select and utilize appropriate Hollow Cathode and Electrodeless Discharge lamps.
• Implement Zeeman and Deuterium background correction to resolve interferences.
• Apply chemical matrix modifiers to stabilize volatile elements in the furnace.
• Execute advanced sample digestion protocols for complex industrial solids.
• Calibrate the AAS system using the method of standard additions.
• Perform routine maintenance on nebulizers, burners, and graphite tubes.
• Diagnose and resolve spectral, physical, and chemical interferences.
• Validate AAS methods according to international regulatory requirements.

TARGET AUDIENCE:

This course is intended for Analytical Chemists, Quality Control Specialists, Environmental Scientists, and Laboratory Technicians working in mining, water treatment, and chemical manufacturing sectors.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
