  9. Ion/electron methods - XRF, XRD, EMPA, Ion beam methods

Brief description

This module will be a practically-based course which will provide training in safe laboratory procedures for the inorganic analysis of environmental materials. The module will start with sample preparation and dissolution, then consider classical analytical techniques and go on to cover a wide range of advanced instrumental analytical techniques. The module will emphasise the importance of quality control and assurance in analytical chemistry and will cover calibration techniques. A series of laboratory exercises will be assessed through laboratory notebooks and practical write ups. The students will also work on a group project to assess the geochemistry of a potential development at a selected green field or brown field site.
