Current Academic Year 2024 - 2025

All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).

As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

Description

To provide students with experience in the safe operation of analytical instrumentation. To promote 'hands-on' development of analytical methods applicable to real-world problems encountered both in industry and academic research. To encourage an interdisciplinary approach to problem solving in a modern analytical laboratory. To apply theoretical knowledge in a practical laboratory setting. To develop record-keeping and presentation skills. To develop inter-personal, team-work and communication skills. To introduced students to modern instrumental techniques. To introduce students to the concepts of sampling and sample handling. To introduce students to preparation, storage and handling of standards and reagents. to introduce students to concepts of instrument calibration and method validation. To analyse the air and water samples taken during the field trip.

Learning Outcomes

1. operate state-of-the-art analytical instrumentation and develop analytical methods for specific problems using this instrumentation. The students will gain hands-on experience with specific instrumentation for spectroscopy, chromatography, atomic absorption spectrophotometry, IR/NMR.
2. appreciate the importance of health and safety in a laboratory setting.
3. understand the protocols necessary for the care of analytical instrumentation.
4. competently write detailed scientific reports based on the analytical methods they use in the laboratory.
5. apply laboratory quality control techniques to the analytical methods that they develop.

Reassessment Requirement Type
Resit arrangements are explained by the following categories:
Resit category 1: A resit is available for both* components of the module.
Resit category 2: No resit is available for a 100% continuous assessment module.
Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
