Environmental AnalysisLaajuus (5 cr)

Objective

Environmental sampling and sample preparation techniques:
• the student will demonstrate competence in the collection of water, soil and air samples and in the analysis of organic and inorganic compounds
• the student will be able to use appropriate sample preparation techniques to ensure the preservation and stability of the samples collected.

Chromatographic sample preparation techniques:
• the student will master a variety of sample preparation techniques, including solid phase extraction (SPE), solid phase microextraction (SPME), liquid-liquid extraction (LLE), and derivatisation for chromatographic analysis
• the student can select and implement a sample preparation method based on the analyte, the matrix and the desired analytical method.

Residual analysis of environmental samples:
• the student will apply advanced analytical techniques such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) for the identification and quantification of residues in environmental samples.
• the student will be able to interpret spectra and chromatograms to infer the presence and concentration of specific compounds.

Indoor air quality assessment:
• the student will learn different sampling techniques to assess indoor air quality
• the student will be able to use methods for the analysis of indoor air pollutants such as volatile organic compounds, radon, carbon monoxide and particulate matter
• the student shall apply appropriate analytical techniques to quantify indoor air pollutants and assess their potential health risks
