Contents: Fundamentals in chromatography and electrophoresis, theory and instrument setup of the most important separation methods: gas chromatography, liquid chromatography (including size exclusion, affinity and ion chromatography), capillary electrophoresis. Introduction into the theory of chromatography and electrophoresis: selectivity and efficiency. System setup of GC and LC: sample input, columns, detectors. Problem solving by GC, planar Chromatography and HPLC. Modern CE.

Contents: Mass Spectrometry - an analytical tool; instrumentation (ionization, mass analyzers, detectors, vaccuum systems); chemical structure information and fragmentation paths; data analysis; typical applications: MS coupled with separation systems (GC-MS, HPLC-MS); MS in bioanalytics and proteomics research.

Assessment and permitted materials

ATTENTION - change in the exam format due to the current situation:

Written online exam with open book format in a limited time period (3 h).

Students will download the questionaires from moodle (extra moodle course for the exam) to their personal computer, answer the questions on the computer (handwritten answers are not allowed) and will upload the answers as a pdf document (Tool "Aufgabe" in moodle) within the given time period. Is it required to draw structures etc., this can be done on an extra sheet of paper. A photo or scan of this additional sheet can be uploaded in addition to the exam pdf. Only correctly submitted exams will be considered for grading.
There will be a test exam focussing on the technical application. The test exam will not be graded.

You need to obtain at least half the points that can be reached (36 out of 72 grading points) to pass. Each teacher prepares a questionnaire based on 24 grading points. To pass the exam you have to reach at least 10 points in each part.
Tests are graded based on the following rukes:
63,0-72,0 points --> sehr gut
54,0-62,5 points --> gut
45,0-53,5 points --> befriedigend
36,0-44,5 points --> genügend
00,0-35,5 points --> nicht genügend

De number of points to be reached for each question varies between tests, but is always given on the papers distributed.

The use of the lecture slides, book and your own notes are allowed.

Signing up is only allowed through uspace, as usual.

Identification: Log in with your u:account in moodle and follow the sign up instructions there.

Questions during the exam? There will be a professor available through BBB during the entire time.

Cheating: Students will confirm by accepting the exam download that they will write the exam without the help of others. There will be a check for plagiarism (turnitin) and also a request for oral recall on the exam. This can be random or considering a cheating attempt. In case of a cheating attempt this will be documented and the exam will not be graded.

If the exam is not submitted properly, the exam is negatively graded.

In case of technical problems, please send a message to the person overseeing the exam.
