Prerequisites

To have completed the subject of Chemical Reactivity, 1st year Degree in Nanoscience and Nanotechnology

Objectives and Contextualisation

In this subject the basic knowledge of Analytical Chemistry and Chemical Analysis must be acquired. The main objective is to establish the concepts and methodologies of work, so that the student can apply them in real practical cases. Some examples of application in the field of analytical nanosystems will be mentioned.

 

The subject is structured in five blocks of homogeneous content but of different duration.

Block 1: The objective of Analytical Chemistry, the analytical process and, above all, the different calibration methods are introduced, as well as basic statistics for its correct use and interpretation of results.

Block 2: Introduction to chromatography. Basic principles; gas chromatography; high resolution liquid chromatography.

Block 3: Brief introduction to the classical methods of wet analysis.

Block 4: Introduction to analytical spectroscopy. Special emphasis will be placed on molecular analysis techniques and the most common atomic analysis techniques will be introduced. The principles and applications of infrared spectroscopy will be described as an example of qualitative analysis.

Block 5: Introduction to electrochemical analysis, especially potentiometric methods and the basic principles of amperometry.

Methodology

The student will carry out three types of activities: directed, autonomous and supervised.

1.- Supervised activities: Attendance is compulsory and is carried out in the presence of a teacher.

1. Theoretical classes: The teacher explains the contents of the subject and answers any questions that the student may have.

2. Problems solving: The knowledge acquired in the master classes and in the autonomous activities of the student, mainly through the study, are applied to the resolution of problems and exercises related to the contents of the subject.

3. Laboratory practices: They involve the performance of practical work related to the contents of the subject.

2.- Autonomous activities: With these activities the student alone, or in group, has to achieve the own competences of the asignatura. These activities include study, problem solving, text reading and bibliography research.

3.- Supervised activities: The student can request tutorials of support for the assimilation of the matter exposed in the classes of theory and problems and for the resolution of the complementary works.

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.

Assessment

1. WRITTEN EXAMS (70%)

A) Partials: there are two partials on the concepts of theory and problems (they eliminate matter). The weight of each part will depend on the distribution of hours and matter between parts, the proportion of each part in the final grade may be modified, which will be indicated in the presentation of the subject. The minimum grade to be able to average between the partials is 3.5.

B) Retaken exams: the student who does not reach 3.5 in one (or both) partials, will have the possibility to retake the exam.

To be able to attend the recovery of the partial or final exams, you must have taken a minimum of 2/3 of the continuous assessment activities and have a minimum grade of 3.5 in each of the partial exams.

You need a minimum grade of 4 from the average of the partials or the global retaken exam to be able to average with the other activities. If this mark is not reached, the subject will be considered suspended and the mark of the resit exam will be recorded in the minutes.

2. CLASSROOM EVALUATION AND DELIVERY ACTIVITIES (15%)

Individual: simulation study of a separation of a sample sample by HPLC

In pairs: presentation of a concept of the syllabus, which will be chosen at the beginning of the course.

3. PRACTICES (15%).

Internship reports. Preparation of an internship report.

Attendance at laboratory practices is mandatory. In the event of non-compliance with safety regulations, a student may be expelled from the laboratory and suspended from that day's practice. In the event of serious or repeated non-compliance with safety regulations, he / she may be expelled from the laboratory and suspended from the subject.

To pass the course, a minimum overallgrade of 5.0 must be obtained.
