CHEM06039 2019 INORGANIC AND CLASSICAL ANALYSIS
This course provides a practical and theoretical introduction to forensic inorganic analytical techniques particularly classical non-instrumental methods of analysis. Fundamental aspects of good laboratory practice in the analytical laboratory are emphasised. The module develops the ability to carry out gravimetric and volumetric analyses with confidence and with a high level of accuracy and precision.
On completion of this module the learner will/should be able to;
Describe the features of a range of classical inorganic techniques used for forensic analysis.
Calculate chemical compositions from raw analytical data in a variety of units and evaluate the reliability of analytical data using simple statistical and quality control techniques.
Develop skills to perform a complex inorganic analysis safely and with confidence.
Record data and maintain records of analytical work in a laboratory notebook in a format required by Good Laboratory Practice and ISO17025.
Write experimental reports concisely, and in proper scientific format.
Teaching and Learning Strategies
This module will be delivered fulltime (or part-time for online modules). This will include lectures, problem based learning (PBL) and laboratory practicals augmented by independent learning and directed learning. This approach is expected to address student learning needs. Moodle will be used as a repository of educational resources and as a means of assessment (e.g. quizzes, uploading assignments and journals). Self-assessment tests and other forms of formative assessment are provided to students to check their own progress towards achieving the learning outcomes of the module and to motivate learning.
Module Assessment Strategies
This module is 100% Continuous Assessment. The continuous assessment will include the following elements: formative assessment through preparation of assignments for discussion at workshops and through pre-laboratory assignments for which answers are given in advance; Two written assessment around mid- semester and at the end of the semester(20%); pre-laboratory and other assignments (20%); assessment of practical laboratory work and records (40%) and of laboratory reports (20%)
