Main themes

The main topics of this course concern electrochemical and spectrochemical analyses, as well as separation methods. For each of the chapters, the theory is described and the important practical steps of these analytical methods are underlined. This course aims to develop professional approach towards the genesis of analytical information (instrumentation, protocols, performances, cautions). A series of practical exercises, presented in a concise and clear manner, on titrimetric and instrumental methods (electroanalytical, potentiometric, spectroscopic and chromatographic) are proposed. The students should rely on their course and on the available literature in order to correctly select the appropriated reactants and define the relevant operating modes. At the end of these exercises, the students should be able to propose clear analysis schemes that can be applied to samples of average complexity.

Aims

This course aims to extend the fundamental formation of 'Analytical Chemistry I' (CHM 1321) to current instrumental analysis methods. The philosophy and strategy of this programme are identical to those described in CHM 1321. This course not only provides excellent practice in analytical techniques, but also allows the rigorous development of experimental schemes and analysis methods, relying on physical chemistry and analytical reasoning. The objectives of the practical exercises are the following: - To help the understanding of the course - To familiarize the students with the theory-experience relationship - To train the students in a professional practice in a chemistry laboratory -To instil a sense of initiative towards practical processes in the students

Content

Course: Molecular absorption spectroscopy, atomic spectrometry and voltamperometric methods: equipment, performances and applications. Electrolysis-based analysis methods: analytical applications. Acid-base reactions in non-aqueous media: solvent types and pH calculations. Practical aspects of chromatography in liquid and gas phases. Exercises: Analysis of samples where application of most of the techniques covered during the course is required. A complete analysis of a 'real' sample is proposed, for which the well-thought-out use of titrimetric and instrumental methods is necessary in order to determine the concentration of several ions of a solution. This process will allow the students: (i) to develop and discuss schemes and analysis methods with rigorous analytical reasoning. (ii) to obtain professional laboratory experience of current techniques. Teaching and learning methods The teaching module will alternate courses to promote significant interaction with the students, and delivery of seminars devoted to problem solving and the study of practical cases concerning topics independently treated by the students (as a direct extension of previous courses or new subjects). The goal of these seminars is to encourage students' reflection and to stimulate more personal and active learning. Written exercises are proposed to test the understanding of the subject. Researching necessary background information, care in preparation of standard solutions and the evaluation and discussion of the quality of results are key factors for the success of the practical exercises.
