Hours of instruction:

Weekly: three hours of lectures + six hours of labwork (3+0+6)

Goals:

To introduce students to the principles of basic electrochemical (conductometry, potentiometry, electrolysis and polarography) and optical methods (UV/VIS-spectrophotometry, flame photometry and atomic absorption), (ICP-OES inductively coupled plasma and ICP MS). Apart from that, students will be introduced to the fundamentals of the analysis of real samples. They will be instructed on how to choose the most appropriate instrumental methods depending on the type of the sample and how to use the computer to process the obtained experimental data and write reports. Within this course students will also learn about the fundamentals of speciation analysis in the environment.

Outcome:

After completing this course, students will be able to work independently and use the appropriate instrumental techniques with the relevant knowledge which will enable them to select the most appropriate way to take and store the samples and to choose the right instrumental method to achieve the required sensitivity and reliability of determination. Apart from that, students will be able to work with available software packages which are used in instrumental chemical analysis.

Teaching methods:

Lectures and experimental (group and individual) exercises.

Extracurricular activities:

As their extracurricular activity, students are obliged to finish drawing graphs and complete each group and individual exercise in case they have not finished the exercises in the class. Apart from that, students are expected to prepare for defending both group and individual exercises.
