Low-temperature and room-temperature phosphorescence, luminescence in organized media.
Fluorescence and phosphorescence spectroscopies in solid phase: optical sensors. Luminescence probes methodologies and luminescence sensor methodologies: flow-through optosensors. Chemoluminescence and sensitized luminescence.
Joaquim de Araújo Nóbrega
Federal Universtity of São Carlos, Brazil
This course will highlight microwave-assisted sample preparation for spectrochemistry techniques, such as FAAS, ICP OES and ICP-MS. Theoretical aspects and experimental parameters including microwave power, reagent temperature, pressure, matrices, chemical compatibility, and practical standard methods will be discussed. Basic features of microwave decomposition methods will be presented for cavity- and focused-radiation microwave ovens. Practical standard methods and special applications based on digestions with diluted acids in closed vessels, the combination of diluted acids and oxygen gas for digestions in closed vessels, microwave-assisted combustion in cavity-type and focused-radiation microwave ovens will be presented. Experimental procedures will be described for biological samples, environmental samples, and technological materials. A wish list of attributes for microwave-assisted sample preparation will be proposed and evaluated considering the state of the art. Major needs will be pointed out.
University of Aberdeen, UK
1.Introduction into metal speciation analysis
The basics of speciation analysis, the “why” and “how” will be focused. The basic ideas of metal speciation in the environment, the transformation and distribution of species will be explored and also discussed the basic concepts of toxicity.
2.Analytical tools for metal speciation analysis
The focus will be directed to analytical techniques and tools, exploring different hyphenated systems for the coupling of chromatography with element selective analysers, notably ICP-MS and AFS. Here, problems and technical aspects of the hyphenations with possibilities and limitations will be discussed. A part of this course will deal with sample preparation issues which are essential for different coupled techniques.
3.Advanced Mass Spectrometry for metal speciation analysis
Advanced aspects of metal speciation, including hyphenation and possibilities with molecular mass spectrometry will be discussed. Simultaneously hyphenated systems to ICP-MS and ES-MS will be discussed and introduced, and examples of applications given. Here we will also deal with quantification issues and strategies
