Having studied or being currently enrolled in Spectroscopic Analysis Methods and Separation Techniques. Have passed the security test (virtual campus).
During practices, students must wear the approved lab coat and safety goggles. In addition to the usual tools to write, they should bring a scientific calculator, a laboratory book and a spatula.
The main objective of the subject is that the student reaches the competences indicated in the corresponding section.
The general objectives are:
1. Apply the fundamental laws and the theoretical principles acquired by the student in the courses of the subjects referenced in Prerequisites section.
2. To familiarize the student with the use of specific instrumentation, the acquisition of data in the laboratory and its interpretation, the introduction to the methods of analysis of data ...
3. To develop in the student a critical mentality that refers to the level of confidence of their measures, calculations and the interpretation of results.
The development of the contents will begin with a one-hour lecture. Here the content and methodology needed for the realization of the two blocks of this subject will be presented. There will be 12 laboratory sessions of 4 hours each, with the contents indicated below.
Spectroscopic methods (5/6 days)
- AAS (Atomic absorption spectroscopy).
- AES (Atomic emission spectroscopy).
- UV-Visible Spectrophotometry.
Chromatographic methods (5/6 days)
- Gas chromatography.
- Liquid chromatography.
This subject consists of two parts distributed according to the methodology and the theoretical knowledge employed. Before beginning the laboratory sessions, there will be one session in the theory classroom about the rules that appear in this Teaching Guide, the latest information and the methodology and contents of the blogs.
The students, in groups of 2 students, will perform 12 laboratory sessions of 4 hours. Students will previously have the scripts of the practices for their preparation. They must enter the laboratory with the script of the practice read and with the calculations that ask for the preparation of dissolutions raised from home.
Students must write in the laboratory booknote all the experimental results and the teacher's explanations. Once the practice is finished, the students will fill out and / or write the report of the practice and hand it in to the professor or through virtual campus depending on the instructions given by the professors. All the results obtained in the laboratory must be presented in tables with the uncertainties and the corresponding units. The graphs must be presented with a title, the magnitudes represented, the corresponding units, the bars of uncertainties and the results of the adjustments if applicable.
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.

The evaluation process follows the principle of continuous evaluation. The overall score will be constituted by the weighted sum of 2 sections: laboratory (60%) and written exam (40%).
Attendance at the classroom and in the laboratory is mandatory. An unjustified lack of attendance involves a zero of the practice. The laboratory score will consist mainly of the qualification of the reports, but may include, with different weights, other concepts such as: prelab tests (short written test to verify that the student has adequately prepared the practice that he/she is going to perform); laboratory notebook; behavior and attitude. The concepts to be evaluated and the corresponding weighting factors will be explained in the presentation of the laboratory. If a student obtains a score <3.5 in the laboratory, or assistance has been less than 85% of practices, the subject will be considered "failed" and the score of the failed laboratory will be the global grade of the subject.
The score of the written exam must be equal to or higher than 4.0 in order to be taken into account in the calculation of the weighted average of the overall score of the subject. If this minimum score of 4.0 is not obtained, a retake exam will be available. If the retake exam does not reach 4.0, the subject will be considered “failed” and the grade of the subject will be the score of the failed exam.
To participate in the retake exam, students must have been previously evaluated in a set of activities the weight of which equals a minimum of two thirds of the total grade of the subject and have reached a global grade equal or higher than 3.5.
In the case of non-compliance with safety regulations, a student may be expelled from the laboratory and suspend the practice of that day. In the case of serious or repetitive breach of safety regulations may be expulsion from the laboratory and suspend the subject.
