The main objectives are:
To achieve these objectives, students should know how:
Theoretical-practical program: Introduction. Instrumental methods of analysis. Factors of selection of analytical methods. Basic concepts of validation. Sample preparation processes (LLE, SPE, SLE and SPME). Spectral methods of analysis. Molecular absorption spectroscopy in ultraviolet (UV) and visible (VIS). Atomic absorption spectroscopy. Flame atomization, electrothermal and ICP. Mercury analysis by cold vapor and hydrides generator for arsenic and selenium determination. Electrochemical methods of analysis. Potentiometric determination with ion selective electrodes. Chromatographic methods. Theory of chromatography. Gas chromatography with flame ionization, electron capture and mass spectrometry detectors. High performance liquid chromatography with ultraviolet/visible and fluorescence detectors.
Laboratory program: The laboratory classes take place in the laboratory of Instrumental Methods of Analysis of DEQ (E105) and 6 groups per class will be formed. Students must do 7 laboratory works, 6 of which in a rotation scheme. In the first week all students will perform the work T0. In the weeks before FEUP’s week, the students will perform the works T1 to T3 in a rotation scheme. The week after FEUP’s week will be reserved for the preparation of the short-term report about one of the laboratorial works already performed (which will be selected by the professor). The works T4 to T6 will be carried out in the remaining weeks in a rotation scheme.
T0. Validation of an analytical method for the analysis of cadmium in soils by flame atomic absorption spectroscopy (AAS) after acid digestion;
T1. Determination of the copper content in an electrical wire by flame AAS;
T2. Determination of the heavy metals content in a soil by ICP-OES;
T3. Determination of the peroxide content in mouthwash by molecular absorption spectroscopy using the standard additions method;
T4. Determination of the salt content (Na+) in a food product by ion selective electrode;
T5. Determination of the concentration of the antibiotic metronidazole in an aqueous solution by HPLC-UV;
T6. Determination of the linalool (essential oil) in plant extracts by GC-FID using the internal standard method.
Theoretical-practical classes: Presentation of the themes with the support of audiovisual tools, emphasizing the application of students’ knowledge to everyday issues and phenomena related with Chemical Engineering; Resolution of key-problems.

Laboratory classes are mandatory to all students, including those who have a special status (article 4, paragraph a) e b)).
To obtain frequency, the students must have necessarily done all the practical works, as well as shown proper preparation and execution of the works and should develop in the laboratory notebook the discussion of the results obtained. This can be requested by the teacher in the following week.
An opportunity is given to repeat one of the works in case of justified absence, provided that the date of replacement of the work is combined with a minimum advance of 2 weeks and to the extent of the laboratory availability.
FG = 0.30 MT + 0.15 RELint +0.25 REL + 0.30 EX
where:
MT – average grade of the two mini-tests of 15 min (T/F). These tests will not be scheduled and they will take place at theoretical-practical classes. Students have to reach a minimum grade of 7 out of 20. If students skip one of the tests or not reach the minimum grade, they can perform this evaluation component at the special examination period.
RELint – grade of the group short-report related to one of the laboratorial works, selected by the professor. The final report (paper version) should be delivered to the professor in the following laboratorial class.
REL – grade of the group report related to one of the laboratorial works, selected by the professor. The final report (PDF file) should be sent to the professor Vítor Vilar by email (vilar@fe.up.pt) until December 26th at 5:00 p.m. and later delivered in paper version until 4:00 p.m. on January 3rd.
EX – grade of exam in the regular examination, performed on 13th December. Open-response questions about the analytical methods studied in the laboratory classes will be done, as well as calculating results and discussion of them. The minimum grade is 7/20.
Students have to reach a minimum grade of 10 out of 20 to complete the course.
IMPORTANT: Obvious cases of plagiarism in any written evaluation component will be penalized with a grade of zero.
Not applicable
An exam at the special examination period, according to the general rules. Students have to attend to the laboratory classes and do all the assignments. Students should have practical frequency and should have done the report (REL). The final classification is given by:
CF1 = 0.80 EE + 0.20 REL
where: EE – exam grade at the special examination period (minimum grade of 7/20).
Students have to reach a minimum grade (CF1) of 10 out of 20 to complete the course.
Students who have attended classes and have a grade to all components of assessment (MT, RELint and REL), but have not passed in the regular examination period, or wishing to undertake improvement of classification, may perform the exam at the special examination period. The final classification CF2 is given by:
CF2 = 0.60 EXR + 0.20 RELint + 0.20 REL
where: EXR – grade of the exam at the special examination period.
Students with practical frequency from a previous academic year, wishing to undertake improvement of classification, must carry out one of the laboratory work in a group (date to be agreed until the end of October). They have to write an individual full report about the obtained results (REL). The final classification CF3 is given by:
CF3 = 0.60 EXR + 0.40 REL
where: EXR – grade of the exam at the special examination period.
Students have to reach a minimum grade (CF2 or CF3) of 10 out of 20 to complete the course.
Repeating students with practical frequency, wishing to be exempted from laboratory classes, must carry out one of the laboratory work in a group (date to be agreed until the end of October). They have to write an individual full report about the obtained results (REL). The final classification is given by:
CF4 = 0.60 EXR + 0.40 REL
where: EXR – grade of the exam at the special examination period.
Students have to reach a minimum grade (CF4) of 10 out of 20 to complete the course.
