KJE-2003 Introduction to analytical chemistry - 10 stp

The course will cover important theory and practical techniques for qualitative and quantitative work in a chemistry laboratory with emphasis on instrumental methods and relevant statistical methods for the treatment and evaluation of experimental data. The following topics will be covered:

• Laboratory safety
• Principles and application of gas, liquid and thin-layer chromatography
• Principles and application of extraction and isolation methodology
• Quantitative and qualitative analysis
• Spectrophotometry
• Infrared spectroscopy
• Nuclear magnetic resonance
• Mass spectrometry
• Substance identification and analysis from complex mixtures
• Scientific report writing

Required: Basic knowledge in chemistry and spectroscopy - i.e KJE-1001 or equivalent.

Recommended: KJE-1003 or KJE-1006 or equivalent.

• understands the principles of chromatography and its practical applications towards quantitative and qualitative analysis (GC, LC, TLC)
• understands the process of isolation, identification and quantification of single components from complex mixtures
• understands the principles and applications of common spectrometric techniques (NMR, MS, UV/Vis and IR)
• has knowledge of common classes of chemical substances and the general process of analysis and quantification of these

Skills

• can write concise reports on experimental findings.
• can assess safety issues associated with laboratory practice
• can conduct experiments independently according to written procedures
• can assess and discuss experimental results
• can analyze data from the methods described above and apply the relevant statistical treatment
• can evaluate and use relevant methods for the qualitative and quantitative analysis of specific problems in chemistry
• can use extraction methods to isolate single components from more complex mixtures

General Competence

• can apply his/her knowledge and skills developed in this course to solve a variety of practical chemical problems
• can accurately communicate chemical terms, theories and problems related to the methods covered in this course through written scientific reports
• can plan and carry out practical work task involving analytical chemistry instrumentations alone or in group
• can participate in advanced courses on the topics covered in this course

The exam consists of a portfolio of written reports and an adjusting oral examination.

The portfolio will consist of a collection of up to 10 scientific reports based on the laboratory exercises performed during the course. Three reports will be comprehensive and up to 7 will be shorter. One round of  feedback will be given for each report before the final submission of the portfolio.

For the evaluation, 2 reports, thereof 1 comprehensive and 1 short, will be selected randomly for grading. The overall grade for the 2 reports is A - F, where F is not-passed.

An adjusting oral exam will be arranged for candidates who passed the portfolio evaluation. The oral exam will cover the whole course content and can adjust the grade by one grade up or down. 

Work requirements: Approved laboratory work, including the lab journal (notes taken during the lab work for each laboratory exercise). 

A re-sit exam will be arranged the next semester or as soon as possible.

A new round of feedback on the complete portfolio will be given before resubmission.

Evaluation will follow the procedure described for the ordinary exam e. i. 2 reports are selected randomly for grading before the adjusting oral exam.

The date for the exam can be changed. The final date will be announced at your faculty early in May and early in November.
