Safety rules:

IMPORTANT! Please check the laboratory safety rules (http://inorg.unideb.hu/oktatas/114) prior to coming to the first instrumental lab! Every student will sign a paper to confirm, that safety rules were read and understood. IMPORTANT!

General informations:

The analytical chemistry laboratory practice consists of two separate parts: classical quantitative analysis and instrumental analysis. That student can start the practice who has taken it in the Neptun, participates in the education of laboratory safety rules and the subsequent exercise.

General info - Instrumental lab

Students must be prepared to every practice. The theoretical part of the lab manuals must be prepared prior to the lab. 1-2 sheets of blank paper is also necessary for writing short tests at the beginning of each lab. Each short test contain questions corresponding the practice of that given day (not the previous practice). Please don't bring your bags to the labs, leave it in the cloakroom, because usually there is not enough place for storing them in the labs.

Participation in the practices is obligatory for everyone. The table of the schedule contains the place (which lab) and the date of every practice, for the different groups. Checking if the students came prepared is usually donw by a short test, but a short oral examination is also an option. Those students who came to the practice without sufficient theoretical knowledge/preparation will be dismissed from the practice (which equals a failed - not performed - practice)!

Lab manuals:

Lab manuals must be completed of the work carried out by the end of the practice, and should be presented to the teacher at the day of the practice. A short theoretical introduction part must be written into the manual about the essence of the given instruments, methods, calculations prior to each practice. The teacher has the right to check if this part was prepared or not at the beginning of the practice, and if it is founf insufficient, the student is dismissed. This introduction should preferably be written by hand. If not so, and the content of the introduction is plaguarized (copied from various sources), the teacher has the right to apply a sanction at his/her discretion. Copying other parts of the manuals from fellow students is sanctioned similarly. Every student must prepare his/her own lab manual on his/her own.

To attach printed/drawn measurement data to the manual, everyone should have tape/glue, stapler, scissors, etc. Lab manuals must be prepared the day after the practice at latest (if the teacher aggrees).

We approve the followings as lab manuals: stapled/bound sheets of papers collected in good order in a folder or A4 spiral notebook. Don't lose your manuals, as you can prove your appereance at the practice only with the manual.

Final grade:

Students obtain grades during each instrumental practice for the short test, lab manual, lab work and in some cases even for short oral examinations. The grade of a practice is based on their average, which is indicated in the lab manual. Thus, students will obtain a grade (1-5) or a fail for every practice.

For chemical engineer and biochemical engineer students the average of all the grades for each instrumental practice will determine the final mark of the instrumental practice. For pharmacy students, it will be added to the classical part's grade.

- A student may fail to complete a lab, if the student does not show up at the practice, or does not hand the manual in until the deadline, or if the student is dismissed (being not prepared or lack of theoretical introduction).

When determining the final grade:

- If there is at least one failed practice it means failing from this subject with denied signature!

- If at least 2 practices' grade is 1, it means failing (1, as final grade).

- In every other cases (every practice is completed and there is max. one grade 1) the final grade is determined according to the average of the individual practices. The teachers have the right to differ from the general rules of rounding in a positive way (e.g. for outstanding activity on the practices) or in a negative way (e.g. for poor quality or copied manuals).

Absence:

Attendance is compulsory at all of the sessions of the laboratory practice. In case of absence you have to give to the instructor medical certificate. In exceptional case one missing is allowed, but the missed practice session must be replaced. Any absence must be indicated to the instructor (e-mail, phone) prior to lab session.

 

General info - Classical (titration) lab

Short written test:

Each week the laboratory session begins with a short test which begins at 14:00 o’clock (not more than 20 minutes). Please, don’t be late! The more you are late the less time you have for the short test. The test is based on the exercises of that week and the previous week (calculations, theoretical background of the determinations, prevention of accidents and possible dangers of handling chemicals). Cell phone mustn’t be used during the short test for calculations!

Lab manual:

During the laboratory session all students have to write a lab manual which should contain the theoretical background of the determinations, the procedure and possible dangers of handling chemicals, all data of the measurements, calculations and conclusions.

Final grade:

Grading is based on three separate factors:

- the average grade of short test written at the beginning of the classical quantitative analysis lab sessions (an average of at least 2.0 is necessary to avoid a ‘fail’ final grade)

-  the average grade of unknown samples at the classical quantitative analysis lab sessions  (an average of at least 2.0 is necessary to avoid a ‘fail’ final grade)

- the average grade of instrumental analysis lab sessions  (an average of at least 2.0 is necessary to avoid a ‘fail’ final grade)

If one of the criterion is not fulfil, the final grade will be the fail and the student have to retake the course the next year.

Information of the classical analysis lab sessions:

- Lab coats and safety glasses must be worn throughout practice. We cannot give you extra lab coat and safety glasses, but without them it is not possible to take part in the lab practice.

- At the beginning of the lab after the short test there will be short demonstration where the instructors give the students some useful information in connection with that week exercises possible dangers of handling chemicals.

- During the laboratory work students have to carry out classical quantitative determinations. In each week unknown samples are provided for the students who must determine the amount of the solute in the unknown samples. Marks will be given for each determination.
