Instrumental Methods of Analysis II
Objectives
The curricular unit aims to provide the fundamentals in the field of Analytical Chemistry of techniques commonly used in the laboratory: spectroscopy, spectrophotometry, mass spectrometry and electrochemistry, but sometimes only from the user''''s point of view. It is therefore intended that the student understands the phenomena at their origin, enabling them to intervene, in the future, both in terms of the development of the technique and in the interpretation of experimental data.
As specific objectives: i) concept of electromagnetic radiation and interaction with matter; i) fundamentals of spectrophotometry, graphite chamber, (furnace), flame, electric arc, ICP, RX diffraction, ii) fundamentals of electrochemical methods, mainly potentiometric methods and cyclic voltammetry; iii) Mass Spectrometry, Fundamentals, Detectors and -analyzers, and ICP MS

Prerequisites
It’s advisable that the student get approval in introductory chemistry lectures such as Instrumental Methods of analysis I, Introduction to physical chemistry, Analytical Chemistry and basic knowledge in Organic and Inorganic Chemistry.
Bibliography
Quantitative Chemical Analysis, D. C. Harris, W. H. Freeman; 10th edition (July 2022)
Notes/summaries supplied by the teacher
Specialized manuscripts.
Teaching method
Lectures supported by data show a projection of figures/plots/text included either in the documentation supplied directly by the teacher or in the recommended bibliography.
Problem-solving sessions.
Computer sessions with presentation of i)linear and non-linear regression, ii) worksheet to evaluate standard deviation that affects linear regression.
Laboratory sessions with five different experiments. 100% Onsite (Laboratory)
Evaluation method
The continuous evaluation has 2 components: theoretical (T), and practical (L)
The final classification is calculated according to:
Final classification =60% x T + 30% L + 10% Seminar
To get approval in the theoretical part, obtaining a positive classification in the final test or official examination is necessary.
The laboratory classification results from:
i) the evaluation and discussion of the laboratories report
ii) Evaluation of questionaries of the remaining experimental works
iii) laboratorial performance
Subject matter
I Introduction to Chemical Analysis. Sample preparation, cleaning techniques.
II Flame AA Atomic Spectroscopy and Graphite Chamber
III EA Atomic Spectrometry, Flame, Chamber, ICP, ICP-MS
IR Mass Spectrometry MALDI TOF MS, ESI-MS, etc.
V Fundamentals of Electrochemistry, Potentiometry, Voltammetry, Cyclic Voltammetry.
