Subject Title
Lab Assay Methods I

Subject Description
This laboratory-oriented subject addresses techniques and methods used in pharmaceutical analysis. Pre-lab and post-lab lectures delve into the theory of separative and analytical techniques and include clarification of relevant pharmaceutical terminology. (Lectures and Labs)

Credit Status
One credit toward the Industrial Pharmaceutical Technology Certificate Program

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Use physio-chemical methods for the identification of raw materials.

2. Demonstrate methods for the assay of finished products according to various pharmacopoeias (or alternate methods used in industry).

3. Explain the standard and purity needed of the raw material (excipient ingredients) used in the drug industry.

4. Examine various techniques used in the analysis of finished products.

5. Demonstrate the techniques used in the analysis of active raw materials used in finished products.

6.Demonstrate familiarity with the various instrumental analysis techniques used in the drug industry such as: Titration, Dissolution and Disintegration, use of Ultraviolet-visible (UV-Vis) and Infrared (IR) spectrophotometers, Van Kel hardness tester, micrometer and analytical balances.

Modes of Evaluation

  • Assignments are due at the beginning of the class on which they are due.
  • A late penalty of 10% per day is assessed for late assignments, including those not handed in at the beginning of class when due.
  • Material will not be accepted after one week following the due date and/or when the marked material is returned to students, whichever comes first.
  • Assignments are to be prepared by computer.

Absenteeism and Exams
  • Students should be aware that absenteeism almost guarantees an inability to achieve satisfactory grades.
  • Students who are absent for an examination due to an emergency (e.g., motor vehicle accident, hospitalization or death in the family) may provide official documentation within five days of the missed exam and be provided a deferred exam at a later date.  Official documentation includes a death notice or an original doctor’s certificate identifying the date, length of time expected absence and the specific reason for the absence.  Examinations missed without official documentation and approval result in a grade of zero.
  • There are no deferred options for missed tests.  The value of missed tests, at the discretion of the Faculty, will be added to other evaluation components

English Proficiency
  • All written work should demonstrate the following characteristics for clarity and conciseness:
-writing is consistent with the rules of English grammar
-spelling and punctuation are correct
-sentences are structured correctly
-main ideas are supported with specific, relevant examples and reasons
-work flows logically through supporting statements/paragraphs
-work is arranged in correct format (e.g., as a report, essay)
-up to 10% of the final grade may be deducted on all work if the above English competencies are not met.

Format for Assignments
  • Students must use the standard, APA style for quoting sources.   Help is available at:

Laboratory Attendance

The laboratory component is essential and therefore it is strongly recommended  that you attend all labs.  Any missed labs must be supported with a legal document with three days of the lab.  Any student who fails to attend 2 scheduled laboratory classes for a 7 week subject and more than 3 laboratory classes for a 14 week subject will not pass the subject.    

Laboratory Safety
Students are required to review and understand the safety procedures and guidelines outlined on the first class and sign the sheet to this effect before beginning work in the laboratory.  Students must also wear a lab coat and safety glasses when conducting experiments.
A student who arrives without the proper safety equipment will not be permitted to participant in the lab but will be asked to leave the class.  The student will receive no grade for the lab missed.

Grading is based on the following marking scheme:
Project 10%
7 Lab Reports (5% each) 35%
Quizzes 15%
Final Exam 40%

Other Evaluation Considerations
The student is expected to comply with the Safety Rules for working in the laboratory, sign the safety contract, and WILL NOT UNDER ANY CIRCUMSTANCES WEAR CONTACT LENSES in the laboratory.  The student will know where all safety equipment is located in the laboratory and will be familiar with WHMIS concepts and signage.
