Description:
COURSE OBJECTIVE: Through experimental exercises the student gets acquainted with the work and methods of work on modern
instrumentation (in all laboratories included in the Applied Chemistry study).

COURSE EXECUTION PROGRAM (elaborate them as precisely as possible according to the teaching weeks):
Exercises are done in a block of 7 weeks, two days a week (average 5.36 hours per day) within
a total estimated hourly rate of 75 hours. Students in groups visit all Departments included in the course and
do the exercises using existing instruments according to the following schedule:
ZOK (2 weeks = 21 hours): Monitoring reactions using GC / MS,
UV / VIS, Fluorescence and HPLC;
ZAK (2 weeks = 21 hours): Chromatography (HPLC / MS, Ion chromatography),
Atomic absorption spectrometry;
ZEK (2 weeks = 21 hours): Voltammetry, EIS, Quartz-crystalline nanoga;
ZOAK (1 week = 12 hours): ICP (Inductively coupled plasma),
Integrated analytical systems.
At the end of each completed exercise, ie problem solving using a certain technique, the code is collocated
teacher / assistant and writes a paper.

DEVELOPMENT OF GENERAL AND SPECIFIC COMPETENCIES OF STUDENTS:
Through experimental work, students get acquainted with the principle of working on modern instruments and acquire practical skills,
advantages and limitations of certain techniques and methods in different areas of their application.
STUDENTS 'TEACHING OBLIGATIONS AND THEIR PERFORMANCE:
Students are required to work on the exercises and at the end of the exercise to colloquize and submit a paper.
