6. Development and Validation of HPLC Methods for Analytical and Preparative Purposes
Sammanfattning : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. LÄS MER
7. New approaches to preparation of macroporous monoliths for use in liquid chromatography
Sammanfattning : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. LÄS MER
8. Miniaturized fluid system for high-pressure analytics
Sammanfattning : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

9. Aspects of Optimisation of Separation of Drugs by Chemometrics
Sammanfattning : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. LÄS MER
10. Supercritical fluid chromatography and two-dimensional liquid chromatography : From new applications to technical innovations
Sammanfattning : Lignin depolymerisation can be utilized to produce value-added aromatic compounds. One of the major challenges in lignin depolymerisation study is the development of effective analytical tools to unravel the huge complexity of the depolymerisation product mixture. LÄS MER
