Basic knowledge of general chemistry. It is recommended to have acquired the basic knowledge and skills taught in the subjects Inorganic Chemistry and Equilibrium, and Fundamentals of Chemistry
Context
The subject Instrumental Analytical Chemistry is taught in the Chemical Engineering Degree as a compulsory subject within the second academic year. It is an introductory subject and also finalist, since it has no continuity in the Study Plan.
Objectives
The Instrumental Analytical Chemistry course aims to introduce the basic knowledge of instrumental analysis techniques, particularly UV-Visible spectroscopy, potentiometric methods, emphasizing the pH electrode, and a brief introduction to chromatography in general as a separation technique of complex samples.
The main objectives of the subject are:
- Describe the rationale and basic instrumentation associated with the techniques studied
- Apply this knowledge to solve chemical analysis problems.
PART I
Lesson 1: Introduction. Instrumental analysis techniques. Classification of instrumental analysis techniques. Basic components of analytical instrumentation. Quality parameters of an analytical instrument. Selection of the analytical method. Sensitivity, detection limit and quantification limit. Calibration. Calibration methods. Regression line. Inaccuracy of the calibration line. Interpolation inaccuracy.
PART II
Lesson 2: Interaction of electromagnetic radiation and matter. Properties of electromagnetic radiation. Spectrum of electromagnetic radiation. Radiation absorption. Beer's law.
Lesson 3: UV-Visible Spectrophotometry. Instrumentation. Fundamentals UV-Visible Absorption Spectroscopy. Applications. Standard Addition Method
PART III
Lesson 4: Introduction to electroanalytical techniques (I). Electrochemical cells: galvanic and electrolytic
Lesson 5: Potentiometry. Redox electrodes: classification of indicator electrodes. Reference electrodes. Liquid bond potential. Ion selective electrodes. El pH electrode. Crystal membrane electrodes. selectivity coefficients. Direct potentiometry: electrode calibration and standard addition.
PART IV
Lesson 6: Chromatographic techniques. Concepts and terminology. Classification according to solute-stationary phase interaction. Gas chromatography. Liquid chromatography. High Resolution Liquid Chromatography (HPLC). Applications.
Methodology
Although the teacher will use the master class to transmit knowledge of the core aspects of each topic, the student must be an active part of the learning process (interactive master class). In this sense, initiatives on inquiry, motivation, and the process of knowing things will be promoted, with the student having to create and adapt them to their own learning process. The master classes will be reinforced with audiovisual support. The teacher will carry out tasks of orientation, guidance and reinforcement of those aspects that present greater difficulty. Abundant bibliographical material will be made available to students, including theoretical content and exercises. To encourage critical reasoning, discussion, and reflection on the part of the student, work groups will be enabled in the problem classes in order to complete the learning process through group discussion.
Satisfaction surveys: Approximately 15 minutes of a class will be reserved, within the calendar established by the centre or by the degree, so that students can answer the surveys to evaluate the teaching performance of the teaching staff and the evaluation of the subject or module.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Evaluation
The evaluation will be individual and will be carried out continuously in the different training activities that have been programmed.
Individual written tests: There will be two partial exams that will include the contents addressed in the different lessons, whose weight will be 90% of the final grade (each partial exam has a weight of 45% of the final grade).
Submission of exercises and papers: Throughout the course the student must submit exercises that will be proposed by the teacher. You will have exercises that will have to be done in class, and others will have to be done as autonomous work by the student. In no case, the days that the exercises will be done will be scheduled and there will be no prior notice. All exercises will be compulsory.
Attitude in training activities: Active participation, face-to-face attendance, as well as the attitude in the different training activities such as lectures, problems, seminars and practical laboratory sessions, will have a subjective assessment by the teacher.
The exercises delivered and the attitude will have a weight in the final grade of 10%
It will be considered NOT EVALUABLE if no partial exam is taken and the make-up exam is not taken.
To pass the subject, it is necessary to obtain a score equal to or greater than 5,0 out of 10 in the FINAL MARK.
Right to make-up exam:
- In the case of not passing the subject by partial plus the work done, the student will have the right to a MAKE-UP EXAM of ALL THE SUBJECT. To pass the subject, it is compulsory to obtain a RECOVERY EXAM MARK equal to or greater than 5,0, but in this case, the final grade will be strictly 5,0 plus 10% of the grade (out of 10) obtained in the exercises.
PARTIAL NOTES= PARTIAL NOTE 1 * 0,50+ PARTIAL NOTE 2 * 0,50
FINAL GRADE (by partial) = PARTIAL GRADE * 0,90 + (EXERCISES + ATTITUDE) * 0,10
FINAL MARK (Ex. Make-up) = MAKE-UP EXAM MARK (all subject) (5,0 if MAKE-UP EXAM MARK ≥ 5,0) + (EXERCISES + ATTITUDE) * 0,10
The final marks of the students who pass the subject can be distributed between 5 and 10, always maintaining the order of the students according to the FINAL NOTE obtained, in order to achieve the distribution between approved, notable, excellent and MHs, that teachers consider appropriate.
Students will have to act honestly throughout the course. Participation in dishonest attitudes (cheating, allowing copying or any action aimed at distorting an evaluation) in any follow-up test or exam will be grounds for a
qualification of "Failed" with a final grade of 0 in the subject, regardless of the rest of the grades obtained by the students involved. In particular, during the written tests, mobile phones or any other telecommunication device
they must be disconnected and stored in the bags or backpacks that will have to be on the platform. In the event that a student is found to be carrying an unauthorized device during the exam and/or follow-up test,
the student will be expelled from the classroom and will have a “Failed” grade in the subject.
