Travaux pratiques d'analyse instrumentale [ WFARM1313 ]

general chemistry ; organic chemistry ; introduction to analytical chemistry ; instrumental analysis

The teacher(s), helped by graduate students and technicians, will discuss the different types of instrumental analysis techniques. The goal is first to give the practical basis to understand the theoretical notions studied during WFARM1312 ; second to explain how to use an analytical instrument in order to obtain relevant results.

At the end of the activity the student will be able to

• Understand the functioning and use measuring electrodes, including pHmeters
• Use, based on written procedures, the different analytical instruments used in the lab
• Build and use a calibration curve for different analytical techniques
• Interpret the data obtained by instrumental analysis

continuous evaluation based on the post-experiment report and, on the evaluation of the student preparation to the day's experiment.

the activity takes place in didactic labs.
