Textbook     Food Analysis by A.S.Alkhalifa and A.dafalla

Course Description:

Introduces basic analytical techniques for food analysis and other biological analysis.  Gravimetric, volumetric, and spectrophotometric methods, gas chromatography (GC), high performance liquid chromatography (HPLC), infrared spectra (IR), and atomic absorption spectrometry are emphasized.

Lectures are presented every  Sunday by prof.a.s.alkhalifa.  You are required to attend a four-hour lab section each week.  A make-up lab will be arranged for illness absences.  Lab reports due 1 week after work is completed.  Class participation is also a part of this course and is strongly encouraged.   There are many ways to do this, including raising questions in class, joining in class discussions, responding to questions raised during class, and being a part of classroom demonstrations.  (Please be sure and check with the professor or staff to make sure you get credit for these.)  Attendance is crucial for this class, and we will try our best to make lectures an enriching experience.

 ExamsPrelim:  saterday,  DEC 17,  1 pm – 2 pm

 Makeup Exams:

A makeup exam will be offered after the scheduled prelim and final.  If you have three exams in 24 hours or a direct conflict, you may sign up for the makeup.  The deadline for signing up for the makeup is one week in advance.   After that time, you need to see Prof. khalifa, and only unforeseen extenuating circumstances will be considered.
