Knowledge and understanding skills. The student will have to know the main analytical techniques available for sampling, purifing, concentrating and preparing real samples before instrumental analysis. He should also have to know differences in treatment of gaseos, liquid, and solid samples. The student should understand the techniques available for sampling, conservation and qualitative and quantitative analysis of chemical components and how to apply them to the real samples. These skills will be verified through a written test.

Ability to apply knowledge and understanding. The student should be able to correctly use the terminology related to analytical chemistry. He will need to know how to choose between sampling techniques, sample handling, and analysis to be applied to a real sample. These skills will be verified through a written test.

Judgment autonomy. The student must be able to make the right decisions on how to deal with an issue related to the sample preparation.

Communicative Skills. The student should be able to clearly describe the analytical techniques studied with appropriate terms and appropriate examples.

Learning ability. The student's scientific growth must be critical and autonomous by using the material provided by the teacher and the self-study material to deepen his knowledge.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Assessment

The assessment of learning requires a written test to verify the student's preparation to choose which chemical-analytical technique is better to use for the sample preparation: framing the problem, sampling, sample handling and analysis. He will also have to demonstrate to know the working principles of analytical techniques, fundamental to make the right choice to his needs. The written examination is judged by a positive judgment.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
