Module Title:Sampling and Separation Science
Language of Instruction:English
Credits: 10
NFQ Level:7
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: This module content previously outlined will be taught in a one hour theory class and one three hour practical session per week. The emphasis will be on the development of good laboratory techniques and experience in the art of chemical separations. Particular emphasis will be placed on the theory and applications of chromatography and other more traditional methods of chemical separation. To encourage an interest in the subject area students may be brought on industrial visits (where possible and appropriate) to illustrate the importance and industrial applications of the module content.
Module Aim: The aim of this module is to impart knowledge of the importance of good sampling procedures and of the fundamental principles of separation methods used in chemical analysis and to provide practical training in this subject area with due regard to best practice and safety.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Describe and discuss the importance of rigorous sampling procedures
LO2 Discuss the principles and background chemistry involved in routinely used separation methods
LO3 Discuss appropriate applications of the techniques studied.
LO4 Perform the designated laboratory exercises with due regard to safety and best practice.
