Attendance
Students are required to abide by KFUPM regulations regarding attendance (Page-38 of the undergraduate bulletin 2006-2009). Regular attendance by students in the course is required. Unexpected absences are not permitted According to University regulations, a DN grade will be immediately reported to the Deanship of Admission and Regulations, as soon as a student becomes eligible (when unexcused absences exceeds one-fifth (6/30) of the total class hours of the course) without waiting until the end of the semester. Reporting of DN grade will be strictly enforced. If you miss an exam, due to illness, a medical report should be submitted to the instructor no later than five working days after the exam. In this case your grade will be obtained from your performance on other exams. A grade of zero will be given for any exam (or quiz) missed without a medical excuse. There will be NO MAKEUP EXAMS or QUIZZES. All students are expected to strictly observe and adhere to the standards of academic conduct as detailed in the undergraduate bulletin (2006-2009).
General Information
The final letter grade will be assessed on the following activities:
Class activities (Quizzes, attendance & homework): 60
First major exam: 70
Second major exam: 70
Final exam: 100
Laboratory: 100
The course introduces the student to the principles and techniques of modern analytical chemistry. Topics including electrochemistry, atomic and molecular spectroscopy and chromatographic separation techniques are stressed. The main objective of the course is to familiarize students with the current instrumental techniques used in various analytical applications through learning their operation, design, problems, optimization, and linking the outcome of these instruments with meaningful information. This aim will be supported by a number of experiments that will be performed in the lab.
Upon completion of the course students should acquire the following capabilities:
Being capable of making the right decision and choice of the suitable analytical method for the selected analytical problem
Understanding the advantages, disadvantages, and limitations of each instrument.
Determine and compare the most important analytical features of each instrument including sensitivity, precision, and accuracy.
Learning the basic measurement principles necessary for the calibration, standardization, and validation of instrumental methods.
Getting the needed experience and knowledge to operate and use effectively the analytical tools and instruments available in the lab which include spectroscopic, chromatographic, and electrochemical analytical methods.
Make proper analysis of the data generated in the lab from these instruments and their relationship to the analytical problem.
Students should ensure that mobile phones are switched off before entry to the classroom.
