There will be an initial seminar (1 hour) which will cover:

- methodology to be developed during the practice sessions

- safety rules and good practices for working in the laboratory

- interpretation and statistical treatment of the results

- relevant information on each of the experimental practices to be developed in the laboratory

- evaluation criteria

Students will be instructed in the use of spectrometry and chromatography equipment with which they will carry out different chemical analysis and/or methodologies to obtain specific analytical information for each sample or for a set of samples. There will be 12 laboratory sessions with a duration of 4 hours. The students will have the guiding notes for the practices in advance. These guiding notes will contain information about the experiment to be carried out so that the students will be able to gather the necessary information and to carry out the calculations nedeed to carry out the experimental part in a fluent manner and to be able to interpret the results critically. It is the student's obligation to prepare the practice and to perform the calculations necessary for the correct development of the experiment.

The experimental data and observations will be written in the laboratory notebook (paper or digital) during the development of the practice. Each couple of students will fill out and/or write the practice report and submit it through a task prepared for this purpose on the virtual campus or in paper format, as indicated by the teaching staff. All results obtained in the laboratory will be presented in tables and/or graphs with the uncertainties and corresponding units.

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 to the initial seminar and to the laboratory is mandatory. An unjustified absence involves a score equal to zero for that 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 <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.

In the event that the subject is failed, but the laboratory score is higher than 6.5, it will not be mandatory to repeat the laboratory practices in the following academic year and the laboratory score will be kept, as long as 75% of laboratory practices were the same as the previous year in which the subject was suspended.

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 5.

In the case ofnon-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.

In the event that a student has not attended more than 20% of the laboratory practices, the subject will be considered as non-evaluable.
