1. 31. Analytical methods for studying polychlorinated naphtalene congener profiles and levels in the Environment

   Författare :Ulf Järnberg; Terry Bidleman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : This thesis describes the development, refinement and application of analytical techniques in conjunction with other methods for studying the environmental occurrence, distribution and transformation of polychlorinated naphthalenes (PCNs). The procedures involve selective high-performance liquid chromatographic fractionation on a styrene-divinylbenzene gel permeation column and 2-(1-pyrenyl)ethyldimethylsilylated silica column combined with high resolution gas chromatography and low resolution mass spectrometry.

   Sammanfattning : This thesis deals with the development of analytical methods for the determination of new antimalarial drugs in biological fluids. The goal was to develop methods that facilitate clinical studies performed in the field, such as capillary blood sampling onto sampling paper. LÄS MER

4. 33. Strategies to explore the membrane proteome of a cell

   Författare :Gianluca Maddalo; Leopold L. Ilag; Peter James; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. LÄS MER

5. 34. Aspects of aquatic sampling and exploratory data analysis of hydrophobic organic compounds

   Författare :Harald Pettersen; Mats Tysklind; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : This thesis is based on seven papers describing studies conducted with samples from the Baltic Sea. It discusses some aspects on the use of multivariate methods for evaluation of data on hydrophobic organic compounds (HOCs) found in the aquatic environment. LÄS MER

7. 35. Development of Enhanced Analytical Methodology in Pesticide Chemistry

   Författare :Tuija Pihlström; Karin E Markides; Bengt-Göran Österdahl; Amadeo Rodríguez Fernández-Alba; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties.
