Learning Achievements (Dublin Descriptors)
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.
Teaching Material
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

Slides distributed during the course.
- 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.
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
