Prerequisite or corequisite units are presented within each program
Learning unit contents
The course introduces basic statistics and the language in analytical chemistry. We develop the concepts of method validation, quality assurance and quality control. Then, the course treats on the conditioning of a sample which often constitutes an essential step for the analysis of its components: the solubilization by wet or dry processes, the separation of unwanted elements. Liquid-liquid extraction and introduction to separation methods. We discuss the basic principles of chromatographic separation mechanism. We detail the different parameters that characterize a chromatographic separation. We discuss the main types of chromatography:
Gas chromatography
Liquid chromatography
Ionic chromatography
Size exclusion chromatography
Learning outcomes of the learning unit
To understand, interpret and apply the various steps of an analysis protocol in order to obtain the best separation process in chromatography. Emphasis is given on the identification and quantification processes in gas and liquid chromatography.
Prerequisite knowledge and skills
The course of general chemistry in 1st bachelor
Planned learning activities and teaching methods
See below
Mode of delivery (face-to-face ; distance-learning)
The lessons (two hours) are illustrated by several experimental demonstrations or data-processing tools. An interruption from 5 to 10 minutes is provided at about the middle of each lesson.
The laboratory work starts at the beginning of the second semester; the purpose are primarily to initiate the students with the particular requirements of the chemical analysis: not to lose anything, not to contaminate, care, cleanliness and method, strict respect of the experimental protocols... The reliability, precision and accuracy of an analytical result depend, of course, in the selection of the method but also on the dexterity and the skills of the analyst.
This activity is part of the teaching module and is mandatory. The student who does not participate at the entire activity and/or provided their reports outside the deadlines fixed will not be admitted at the exam.
Recommended or required readings
The course notes as well as the handbook of laboratory work are available 'aux Presses Universitaires'
A copy of the powerpoint slides are also available.
No particular material (except the apron and safety glasses) is necessary for the laboratories. As supplementary information, the consultation of the following works is recommended:
- ETUDE ANALYTIQUE DES REACTIONS CHIMIQUES DANS L'EAU by J.Y. GAL (TEC et DOC-LAVOISIER, Paris 1989)
- ANALYTICAL CHEMISTRY by D.A.SKOOG, D.M. WEST and F.J HOLLER. 3rd Edition (2015)
Assessment methods and criteria
The examination in june is oral but the student has at least one hour for preparation.
Three scores are assigned to laboratories and it concerns: the sum of the points of N manipulations/n, an interrogation and the test of laboratory.
The oral examination stands for 70%: the laboratory work for 30% . Note: when the score of the oral examination is lower than 10, the points of the laboratory works are not taken into account.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session
Teaching methods implemented : distance-learning
The first five courses were given in a face-to-face setting. The next five courses are given remotely by e-learning videoconference due to confinement. The dates were agreed upon between April 20 and May 15, 2020.
The course notes as well as the handbook of laboratory work were made available
A copy of the powerpoint slides are also available.
Assessment subjects
The content is the same as originally planned. See detail above.
Concerning the practical works, the subject matter for the examination is limited to TPs that were taken place face-to-face, i.e. until Friday 6 March 2020.
Assessment methods
The in-session exam is an oral at distance, the practical arrangements will be discussed during a videoconference with all the students.
Two scores are assigned to laboratories and it concerns: the sum of the points of n manipulations/n until March 6th 2020 and the exam of laboratory that will be organised at distance as a written exam.
The oral examination stands for 70%: the laboratory work for 30% . Note: when the score of the oral examination is lower than 10, the points of the laboratory works are not taken into account.
