7 The Analytical Problem
I Seminar 7.1
Solving an Analytical Problem in the Environmental Domain
The Polycyclic Aromatic Hydrocarbon Content in the Atmosphere
• Learning objective
To understand how a specific analytical problem in the environmental domain
is to be approached and solved.
• Literature
"Airborne Particulate Matter", T. Kovimtzis and C. Samara, Springer, Berlin,
1995, Chap. 9: "Analysis of Organic Particulate Matter", by C. Samara (pp.
233-252).
• Procedure: Aspects to be considered
• Describe PAHs (types, families) .
• The impact of PAHs on human and animal health.
• Sources of atmospheric PAHs.
• The organic fraction of suspended matter in the atmosphere.
• Sampling: Distribution of PAHs between particulates and the vapour
phase. Types of filters.
• Concentration and clean-up from the sampling filter.
• Systems for discriminate determination of PAHs in the clean concentrates:
- GC with conventional detectors.
- GC-MS.
- LC with conventional detectors.
- LC-MS.
• Standards for calibration and global evaluation.
• Validation of the procedure.
• Discuss the features of the response to the information needs raised by the
environmental problem.
Seminar 7.2
Solving an Analytical Problem in the Industrial Domain
Characterization of Soaps
• Learning objective
To introduce an analytical problem related to industrial production.
• Literature
"Official and Standardized Methods of Analysis" (3rd edn), C. Watson (Ed.),
Royal Society of Chemistry, 1994, pp 427 - 445.
• Procedure: Issues
• General description of soaps (commercially available types).
• Definition of the key chemical features of soaps that dictate their quality.
