Description
Analytical chemistry is the study of the separation, identification and quantification of chemical compounds and elements. It underpins forensic science, clinical analysis, environmental analysis and many industries such as mining and manufacturing.
In this subject students develop the theoretical and practical knowledge necessary for a future career as an analytical chemist in forensic science, the pharmaceutical industry and other industrial enterprises in which high-level analytical skills are required. The subject introduces the major analytical instrumental techniques and methods: high performance liquid chromatography (HPLC); ion chromatography (IC); gas chromatography (GC); capillary electrophoresis (CE); and spectrometric techniques for elemental analysis such as inductively coupled plasma mass spectrometry (ICP-MS) and microwave plasma atomic emission spectrometry (MP-AES). Students develop sample preparation approaches for each of these instrumental techniques including solid phase extraction and liquid–liquid extraction, method validation strategies and statistical evaluations of analytical data.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Explain in detail the theoretical concepts for each of the instrumental techniques |
|---|---|
| 2. | Use and apply various sample preparation methods appropriately and efficiently |
| 3. | Proficiently operate and apply each of the instrumental techniques and generate high quality analytical data |
| 4. | Apply knowledge and critical thinking skills for data interpretation |
| 5. | Design an experiment with appropriate application of instrumentation to analyse samples |
| 6. | Prepare a scientific journal report |
| 7. | Work collaboratively in a research team |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of following course intended learning outcomes:
- Demonstrate theoretical and technical knowledge of organic, inorganic, analytical, and physical chemistry and be able to explain specialised knowledge in one or more sub-disciplines. (1.1)
- Evaluate scientific evidence and apply effective experimental design, analysis and critical thinking to test current chemistry knowledge. (2.1)
- Work autonomously or in teams to address workplace or community problems utilising best scientific practice, and to act safely and responsibly in chemistry laboratory and practical settings. (3.1)
- Design creative solutions to contemporary chemistry-related issues by incorporating innovative methods, reflective practices and self-directed learning. (4.1)
Contribution to the development of graduate attributes
The Faculty of Science lists six graduate attributes that students will develop during their course at UTS. This
subject is intended to develop five of those attributes:
1. Disciplinary knowledge
The workshops, online material and practicals are designed to introduce you to analytical instrumentation; including HPLC, IC, GC, CE, along with spectrometric techniques for elemental analysis such as ICP-MS, and MP-AES; and its appropriate application to analytical problems.
2. Research, Inquiry and Critical Thinking
The practical sessions are designed to develop the necessary practical skills for core competency as analytical chemists. This is achieved by five introductory practicals that cover a range of analytical instrumentation; and a three week mini-project that requires the development of an analytical method for an analysis of real world sample by one of the analytical techniques from the introductory practical sessions. The design, execution and interpretation of the analysis are performed by you with the guidance of the demonstrators. This ensures the development of critical thinking skills and initiative.
3. Professional, Ethical and Social Responsibility
This subject is designed to foster logical thought and problem solving skills. Specifically, the basic knowledge of each analytical technique is attained from the lectures and strengthened during the laboratory sessions. This knowledge is then applied to the mini project with an inquiry-based approach - the analytical problem at hand is solved by you as there is no “recipe”. This requires a literature review; design and execution of the experiment; collection and interpretation of data; and reporting of the data in a scientific journal format. The skills developed during this process are gathering, evaluating and using information from sources such as databases, research and review articles, textbooks, catalogues and technical reference books; operation of state of the art analytical instrumentation; troubleshooting approaches; experimental design; data interpretation; working within a team; leadership; written and oral skills.
Self-discipline is also fostered through active participation in lectures, which require you to take notes to reinforce your understanding of the subject concepts. The extent to which you attend lectures and take notes is indirectly assessed through the final exam.
Teamwork is developed as you work in groups through collection, collation and analysis of data for the mini-project. Tasks must be delegated among the group each week to enable all students time to complete various practical components. Group discussion of experimental data at the final data collection stage will help to develop group contribution to interpretation of findings.
4. Reflection, Innovation, Creativity
The introductory laboratory sessions and mini-project will prepare you for independent research; and build the foundations for you to apply new information and techniques to solve problems related to analytical chemistry and forensic science. The laboratories are undertaken in a collaborative framework that facilitates peer discussion; peer review; and provides opportunities for reflection and implementation of feedback.
Teaching and learning strategies
There are 10 x 2 hr scheduled workshops and 11 x 4 hr laboratory sessions.
Workshops in weeks 2, 4, 7, 9 and 10 will be conducted face-to-face on campus. Every other week, the workshop will be conducted online. Prior to any on campus workshop, students are expected to work through the online material. This will prepare the student for the workshop activities.
The practical sessions are conducted face-to-face on campus. The practicals will be performed in collaborative groups and are designed to practice the theoretical aspects presented in the lectures. Instantaneous feedback will be provided by the demonstrators during the practical sessions. The demonstrators will also provide assistance with experimental design and method development procedures.
The project will require students to design and perform an analysis of a real world sample with one of the five instrumental techniques from the introductory sessions. Students will review the literature and under the guidance of the demonstrators propose various strategies to undertake the analysis. The mini-project will instil in the student necessary critical thinking and practical skills required by analytical chemists in the workplace.
Content (topics)
Workshops and online material
You will learn about the field of analytical chemistry, methods of analysis, separation mechanisms and theory of modern analytical techniques. The importance of method validation will be highlighted and appropriate statistical approaches demonstrated to ensure that your analytical methods are “fit for purpose”. Specific content will be presented on core analytical instrumentation, contextualised with ongoing research initiatives at UTS, ensuring relevant and interesting application examples. For on campus workshops, in class activities (worksheets) will be completed to reinforce the material.
Practicals
The practicals consist of three foundational sessions in which the student will be introduced to a core analytical instrument via quantification of various analytes in a variety of samples. The practicals will be performed in groups necessitating a collaborative approach for successful outcomes. Each of the foundation practicals will be assessed in a short report format requiring submission of results. The reports will be marked on the quality of the data, and accuracy of the analysis.
The major analytical project is performed over six weeks where the students will undertake a contemporary analysis on one of the instruments available in the undergraduate laboratory. It is expected that the experimental design, method development and quantification will be driven by the students. The demonstrators will provide feedback and guidance throughout each session. The mini-project will be assessed via a long report format requiring a literature review and formal scientific report, as well as their laboratory notebook.
Learning
Quizzes will be conducted to test understanding of key concepts. Quizzes will be conducted during practical class time.
Attending scheduled face-to-face classes, taking notes, active participation in class and attempting all assessment items is crucial to a full understanding of the subject content. Attendance at practicals and face-to-face workshops will be recorded.
