16. Chiral packed capillary chromatography using an in-column immobilized selector : With special emphasis on vancomycin
Sammanfattning : 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. LÄS MER
17. Heterogeneous Adsorption in Chiral LC
Sammanfattning : The adsorption of chiral drugs on proteins immobilized on silica shows an heterogeneous adsorption behavior on multiple sites. The theory of nonlinear chromatography was used for a systematic study on this behavior - linear chromatography can only measure the "global" retention. LÄS MER
18. Towards the Rational Design of Molecularly Imprinted Polymers
Sammanfattning : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. LÄS MER

20. From achiral to chiral analysis of citalopram
Sammanfattning : Within the field of depression the “monoamine hypothesis” has been the leading theory to explain the biological basis of depression. This theory proposes that the biological basis of depression is due to a deficiency in one or more of three key neurotransmitter systems, namely noradrenaline, dopamine and serotonin which are thought to mediate the therapeutic actions of virtually every known antidepressant agent.
