Prerequisites
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
Objectives
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.
Learning outcomes
- Develop critical thinking and reasoning
- Identify simple organic compounds from the spectroscopic and analytical properties of their functional groups and relate the structural characteristics with their physical and chemical properties.
- Develop a capacity for analysis, synthesis and prospection.
- Work autonomously.

Learning activities and methodology
| Title | Hours | ECTS | Learning outcomes |
|---|---|---|---|
| Theory classes | 20 | 0.8 | |
| Scheduled tutorials | 3 | 0.12 | |
| Autonomous study | 44 | 1.76 | |
| Problems and exercises | 5 | 0.2 |
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.
Students who repeat a course are strictly subject to the same assessment criteria as newly enrolled students.
The use of AI is prohibited in all evaluable written tests.
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.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Realization of two partial written tests | 100% | 2 | 0.08 | 1, 3, 4 |
| Carrying out work and solving problems. | 10% | 1 | 0.04 | 1, 2, 3, 4 |
Communication between the professor and students will take place in person in the classroom or, preferably, via email and the UAB's virtual campus platform.
Reviews of the written exams stipulated at the beginning of the course will be scheduled for a specific day, time, and location, and students will be notified in advance via the UAB's virtual campus.
The awarding of a grade of MH (Honors) will be at the discretion of the responsible professors involved. To qualify for this grade, students must achieve an overall numerical score of 9.0 or higher on the assessment.
Continuous Assessment
Assessment will be individual and ongoing throughout the various scheduled learning activities.
Individual Written Tests: Two midterm exams will be administered, covering the content addressed in the different lessons. These exams will account for 90% of the final grade (each midterm exam accounts for 45% of the final grade).
Submission of Exercises and Assignments: Throughout the course, students will be required to submit exercises assigned by the instructor. Some exercises will be completed in class, while others will be independent work.
Under no circumstances will the dates for completing exercises be scheduled, and no prior notice will be given. All exercises are mandatory.
Attitude in Learning Activities: Active participation, attendance, and attitude in various learning activities, such as lectures, problem sets, seminars, and practical laboratory sessions, will be subjectively assessed by the instructor.
Failure to take any midterm exams or the makeup exam will result in the course being considered NOT EVALUATED.
VERY IMPORTANT!! To pass the course, you must obtain a score of 5.0 or higher out of 10 in the FINAL GRADE (based on partial exams) and a grade of 5.0 or higher in the PARTIAL EXAM GRADES.
PARTIAL EXAM GRADE = PARTIAL EXAM GRADE 1 * 0.50 + PARTIAL EXAM GRADE 2 * 0.50
FINAL GRADE (based on partial exams) = PARTIAL EXAM GRADES (if PARTIAL EXAM GRADE ≥ 5.0) + (EXERCISES + ATTITUDE) * 0.10
Right to a Retake Exam:
- If a student fails the subject based on partial exams and completed assignments, they will be entitled to a RETAKE EXAM covering the ENTIRE SUBJECT.
To pass the subject, a RETAKE EXAM grade of 5.0 or higher is required. However, in this case, the final grade will be strictly 5.0 plus 10% of the grade (out of 10) obtained on the assignments.
FINAL GRADE (Retake Exam) = RETAKE EXAM GRADE (entire subject) (5.0 if the RETAKE EXAM GRADE ≥ 5.0) + (ASSIGNMENTS + ATTITUDE) * 0.10
Right to a resit exam (single assessment):
- If the FINAL GRADE (single exam) is below 5.0, the student will be entitled to a REMATCH EXAM covering the ENTIRE SUBJECT.
To pass the subject, a REMATCH EXAM GRADE of 5.0 or higher is required, but in this case, the final grade will be strictly 5.0 on the academic transcript.
The resit exam will be exactly the same as the one taken by students who opted for continuous assessment, as will the exam date.
FINAL GRADE (Rescue Exam) = REMATCH EXAM GRADE (entire subject)
The final grades of students who pass the subject will be distributed between 5 and 10, always maintaining the ranking of students according to their final grade, in order to achieve the distribution among pass, good, excellent, and honors that the professors deem appropriate. Students must act honestly throughout the course. Participation in dishonest behavior (copying, allowing others to copy, or any action aimed at distorting an assessment) in any progress test or exam will result in a failing grade with a final grade of 0 in the subject, regardless of the other grades obtained by the students involved. In particular, during written tests, mobile phones or any other telecommunications device must be switched off and stored in bags or backpacks, which must be placed on the examination board. If a student is found to be carrying any unauthorized device during the exam and/or follow-up test, the student will be expelled from the classroom and will receive a "Fail" grade in the subject.
