Learning outcomes

Thiscoursehas been designed to blend thebasic knowledgeofgeneral analytical chemistry with instrumental analytical chemistryin order to bring it nearer to the needs of the actual work ofan industrial chemist. At the end of the course students should acquire a specific knowledge in the field of applied analytical chemistry. Since the course is part of a curriculum of studies inherent to materials, the focus will be on those aspects of the analytical chemistry that have particular importance in this specific field.

Course contents

 Introduction to sampling. Definitions. Types of samples. Sampling plan. Sampling of solid, liquid and gas materials. Sampling uncertainty and other source of uncertainty in the final result.

Teaching methods

Lectures integrated by exercises related to the discussed topics.  Simple Lab tests could be carried out to better understand the topics discussed during the theoretical lessons.

The frontal activities will be accompanied by non-binding educational verification tests for admission or evaluation under consideration.

Student products as well as all teaching material will be shared on an online platform.

Assessment methods

Assessment of the course will be via an final oral exam (interview) which aims to verify the acquisition of the learning outcomes expected from the knowledge of the topics which constitute  the program of the Course. The ability of the student to critically and methodologically face the solution of an analytical problem will be privileged. It will be particularly appreciated the achievement of an organic view of the learned topics together with their critical application to real problems and the command of the specific language to analytical chemistry.

Teaching tools

Lectures and class-room activities are carried out with the help of transparencies and video-projection. The teaching material is available  on on-line platform.

Classroom Response Systems ("Clickers" and Kahoot) will be used for the purpose of carrying out learning checks.
