ANALYTICAL CHEMISTRY LABORATORY AND INSTRUMENTAL - MOD.1

The teaching of Instrumental Analytical Chemistry is part of the core educational activities of the three-year degree course in Chemistry and Sustainable Technologies, aimed at providing students with the appropriate preparation to deal with a chemical problem in its various articulations and with the appropriate use of current technical-scientific language.

The course is divided into two modules (defined as Module 1 and Module 2) of theory lessons . Both modules have common training objectives listed below:
1. To provide knowledge of the general principles on which the instrumental analytical techniques most commonly used in chemical analysis laboratories are based.
2. To provide knowledge on the functioning of the instrumentation and on the modality of reading the responses obtained from the different types of instruments and their correlation with the theoretical aspects dealt with.
3. Develop critical sense that allows students to evaluate the potentials, advantages and limitations of the various instrumental analytical techniques studied.
4. Introduce the students to the conscious evaluation of the role of instrumental analytical methods in the specific field of quality control.
5. Develop skills in the evaluation and reliability of an analytical data.
6. Develop skills to apply an appropriate experimental approach to scientific investigation.
The expected results are defined according to the different contents of the two modules of the teaching of Instrumental Analytical Chemistry.

Knowledge and understanding
A) Knowledge and understanding of the fundamental principles of separation instrumental analytical techniques and of the laws that govern them.
B) Knowledge and understanding of the elements that make up the instruments with which analytical measurements are performed by means of chromatographic and mass spectrometric techniques and combinations thereof.

2. Ability to apply knowledge and understanding
A) Ability to use the laws and knowledge learned to establish, from a theoretical point of view, the performance of the tools and the results expected from their use.
B) Knowing how to choose the most suitable instrumental apparatus to perform an analytical measurement on samples characterized by different degrees of complexity.

3. Ability to judge
A) Ability to evaluate the quality of the responses obtained from the different analytical instrumentation considered.
B) Knowing how to identify anomalous instrumental responses generated by the electronic and electrical components that constitute the considered instrumentation.

4. Communication skills
A) Knowing how to describe, both in written and oral form, the theoretical aspects treated using an appropriate language, scientifically correct and with consistent logic.
B) Knowing how to describe, in both written and oral form, the different parts that make up standard tools in relation to the analytical techniques considered.

5. Learning skills
Develop the ability to take notes identifying autonomously the salient aspects of the analytical techniques and methods based on the different instrumental analytical techniques considered.

To have reached the educational objectives of: mathematics institutions with exercises - 1 and 2, Physics 2, Analytical chemistry, General and inorganic chemistry, possibly (but not necessarily) having passed the examination of these teachings.

To achieve the training objectives and the expected learning outcomes, the contents developed in Modules 1 are:
1. General introduction to instrumental analytical methods. Definition of the performance of an analytical method: detection limit, standardization, calibration, linearity range, sensitivity and selectivity.
2. Introduction to spectrophotometric methods. Electromagnetic radiation. Quantitative aspects of spectroscopic measurements. Instrumentation for optical spectroscopy.
3. Introduction to atomic spectroscopy. Absorption spectroscopy, emission and atomic fluorescence. Sample atomization techniques.
4. Molecular spectroscopy: Introduction to molecular absorption spectrophotometry in ultraviolet and visible. Components of the instrumentation. Application of UV-vis molecular spectroscopy. Quantitative analysis.
5. Introduction to electroanalytical chemistry. Recall of the fundamentals of electrochemistry: electrochemical cells, cell potential, Nernst's law. Types of electrochemical methods of analysis.
6. Potentiometric analytical techniques: general principles; metal, membrane, ion-selective and enzymatic indicator electrodes; reference electrodes. Instruments for measuring cell potential.
7. Voltammetry: general principles. Excitation signals and instrumentation. Chronoamperometry - Cottrell equation. Cyclic voltammetry - Randles-Sevcik equation. Voltammetry applications.

As support for the study, the various texts of analytical instrumental chemistry at the university level are acceptable. However, one of the following texts is suggested:

- Holler F.J., Skoog D.A., Crouch S.R., Chimica Analitica Strumentale, EdiSES, Napoli, 2009.
- Skoog D.A., West D.M., Holler F.J., Crough S.R., Fondamenti di Chimica Analitica, EdiSES, Napoli, III ed. (2015), op. II Ed.(2005).
- Skoog D.A. , Leary J.J, Chimica Analitica Strumentale, EdiSES, Napoli, 2000.
- Harris D.C., Chimica Analitica Quantitativa, seconda edizione, Zanichelli, Bologna, 2005.
- Rubinson K.A., Rubinson J.F., Chimica Analitica Strumentale, Zanichelli, Bologna, 2002.
- R. Kellner, J.M. Mermet, M. Otto, H. M. Widmer, Chimica Analitica, Edises

The assessment of learning related to the theoretical part of the teaching of analytical instrumental chemistry, module 1, is carried out by means of an oral examination. The exam consists of a series of open questions related to the theoretical and applicative aspects of the different analytical techniques dealt with in the lessons. The proposed questions are of different levels: comprehension, application, analysis, synthesis and critical evaluation.

The final mark of the Teaching Analytical Chemistry course is composed of the arithmetic mean between:
- the oral examination of Module 1
- the oral examination of Module 2
- laboratory

Teaching will take place through lectures in which the theoretical bases concerning spectroscopic and electrochemical instrumental analytical techniques will be presented and discussed.
