66766 - Complements of Analytical Chemistry and Strumental Analysis

Learning outcomes

This course has been designed to blend the basic knowledge of general analytical chemistry with instrumental analytical chemistry in order to bring it nearer to the needs of the actual work of an industrial chemist. At the end of the course students should acquire a specific knowledge in the field of applied analytical chemistry.

Teaching methods

Lectures integrated by exercises related to the discussed topics.

Assessment methods

Assessment of the course will be via an oral exam which aims to check the knowledge of the issues listed in the section "Course content".

The exam will be passed if the student answers correctly to the majority of the questions raised by the teacher.

Teaching tools

Lectures and class-room activities are carried out with the help of video-projection. The teaching material is available to the students.
