17. Chiral packed capillary chromatography using an in-column immobilized selector : With special emphasis on vancomycin
Abstract : Packed fused silica capillary columns have been used for enantioseparation of drugs and related compounds. The technique to prepare the chiral stationary phase (CSP) involved a reductive amination of aldehyde functionalized silica with a chiral selector. The immobilization was performed in the packed column, thereby minimizing the use of selector. READ MORE

18. Capillary electroseparations with mass spectrometric detection Nanoparticle-based continuous full filling and applications for complex sample matrices
Abstract : One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. READ MORE

19. Advances in analytical methodologies for studies of the platinum metallome in malignant cells exposed to cisplatin
Abstract : The scientific progress about the important chemotherapeutic drug substance cisplatin (CDDP) and its function has often been rendered by data difficult to interpret, and still many questions about its mode of action remains to be clarified by the scientific community. However, studies of CDDP possess a high complexity due to; i) low intracellular concentration, ii) many potential biomolecule targets, iii) poor or unknown stability of the intact drug and its biomolecule adducts and iv) complex and varying sample matrices.

20. Analysis of Degradation Products from Wood and Methods for Detoxification of Lignocellulose Hydrolysates
Abstract : In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. READ MORE
