1. Solid phase microextraction (SPME) applied to studies of polyamide 6.6 long-term thermo-oxidation and In-plant recycling
Sammanfattning : .... LÄS MER
2. Chromatography and extraction techniques for new evaluation methods of polyolefins long-term performance
Sammanfattning : Chromatography and extraction techniques, and also chemiluminescence have been utilized to develop new rapid and informative tools in the evaluation of long-term properties and environmental effects of polymeric materials. Methods were developed for classification of materials and for early and rapid degradation detection. LÄS MER
3. Determination of Volatile Sulfur Compounds in Air and other Gas Matrices : Development and Applications of Solid-Phase Microextraction
Sammanfattning : Volatile sulphur compounds (VSCs) are frequently emitted during bioindustrial activities, such as production of biogas, sewage treatment, landfilling, pulpmilling, and the slaughtering of animals and meat processing. VSCs are reactive and malodorous, and they can also be detrimental to human health, therefore it is of great interest to be able to analyze these compounds. LÄS MER
4. Applications of Solid-Phase Microextraction to Chemical Characterization of Materials Used in Road Construction
Sammanfattning : Environmental and health aspects of road materials have been discussed for a long time, mostly regarding bitumen and bitumen fumes. However, just a few studies on other types of road materials have been reported. LÄS MER
Sammanfattning : In the work underlying this thesis solid-phase microextraction (SPME) was evaluated as a passive sampling technique for organophosphate triesters in indoor air. These compounds are used on a large scale as flame-retarding and plastizicing additives in a variety of materials and products, and have proven to be common pollutants in indoor air. LÄS MER
