Learning activities and teaching methods
Monologic (reading, lecture, briefing)
Learning outcomes
The overall goal of this course is to enable the students to acquire knowledge in the concepts of atomic spectrometry for analytical applications and to familiarize them with different analytical methods focused on identification and determination of elements. The students are introduced to the principles of inorganic analysis, matrix effects, detailed instrumentation, operation and interpretation of data.
At the end of the course the students would understand principles and procedures of methods of inorganic elemental analysis and are able to choose adequate method for solving a particular analytical task.
Prerequisites
Knowledge of analytical chemistry on the level of basic courses Analytical chemistry I and Analytical Chemistry II.

Assessment methods and criteria
Written examination

Theoretical knowledge in the field of selected atomic spectrometry methods will be verified by a written exam.
