Subject Title
Laboratory Assay Methods for NHP Formulation

Subject Description
In this course students learn laboratory best practices, techniques, methods, instrumentation and knowledge of Laboratory operations for analyzing NNHPs. Course entails lectures, case studies and practical laboratory analysis.

Credit Status
One credit toward the Fundamentals of Natural Health Products Certificate Program

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

  1. Identify the NNHP requirements for laboratory operations and prepare testing specifications according to NNHP guidelines using a Natural Health Product.
  2. Perform an analysis of a natural health product in order to demonstrate quality, purity, safety and efficacy of a given product to ensure it meets requirements of NNHP regulations.
  3. Explore the Methodologies and Instrumentation used in analysis of Finish Products NHPs. Physical, purity and actives meet label claims.
  4. Perform various testing methods used in analyzing NNHP: Physical testing, Identification assays, Microbiological testing while using proper techniques and following Standard Operating Procedures and Good Manufacturing Practices.
  5. Evaluate and establish routine procedures for Out Of Specification (OOS) results for the Chemistry and Microbiology Laboratories.
  6. Assess, discuss and create the testing specifications requirements of NNHP.

Unit 12 LAB # 6 ICP-MS
To quantitatively determine minerals in raw materials and finished products by ICP-MS
Examples: Vanadium, Chromium, Nickel, Selenium, Molybdenum, Tin, Magnesium, Phosphorus, Potassium, Calcium, Manganese, Iron, Copper, Zinc and Sodium.
Unit 13 Out of Specifications and how they link to Quality Assurance investigations. Laboratory’s roll in major investigations
Unit 14 Hand in Case Study / Final exam
NNHP Assessment ( Assignment)
Example: Select a current NNHP product (Vitamin, Mineral, Multi, Single, Herbal, etc. products) and from the label claim explain what would have to be analysed, testing specifications, methods, instrumentation (if required), regulations and create the entire report including the laboratory supporting documentation. Perhaps they will be able to analyse their own product during this course? (At least in one lab?)

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:  http://library.senecacollege.ca

Grading is based on the following marking scheme:
Practical Labs (6) 60%
Assignment (1) 20%
Final Exam 20%

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.
