  2. 21. Capillary zone electrophoresis for the analysis of low molecular weight organic acids in environmental systems

    Author : Jessika Hagberg; Bert Allard; Stefan Karlsson; Anders Düker; Patrick van Hees; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary zone electrophoresis; capillary zone electrophoresis-electrospray ionization-mass spectrometry; low molecular weight organic acids; pKa; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Capillary zone electrophoretic (CZE) methods were developed to identify and quantify low molecular weight (LMW) organic acids in environmental samples. Sensitivity and selectivity were optimised by adapting the background electrolyte to the characteristics of analytes, and by using different modes of detection and injection. READ MORE

  4. 22. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis

    Author : Eivor Örnskov; Staffan Folestad; Karin E. Markides; Morteza Khaledi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis CE ; micellar electrokinetic chromatography MEKC ; drug; liposome; microemulsion; coating; pKa; lipophilicity; multivariate analysis; molecular descriptor; hierarchical analysis; passiv absorption; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. READ MORE

  5. 23. Molecularly Imprinted Matrices for Electrochromatography

    Author : Leif Schweitz; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; capillary electrophoresis; enantiomer; film coating; microparticle; continuous bed; monolith; molecular imprinting; capillary electrochromatography; Kemiteknik och kemisk teknologi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. READ MORE

  6. 24. Managing and Exploring Large Data Sets Generated by Liquid Separation - Mass Spectrometry

    Author : Daniel Bäckström; Per Sjöberg; Rolf Danielsson; Thomas Moritz; Uppsala universitet; []
    Keywords : Analytical chemistry; liquid chromatography; capillary electrophoresis; capillary electrochromatography; mass spectrometry; electro spray ionization; chemometrics; multivariate data analysis; peptide; biomarkers; fingerprints; PCA; alignment; data compression; ANOVA; target correlation; data management; Analytisk kemi;

    Abstract : A trend in natural science and especially in analytical chemistry is the increasing need for analysis of a large number of complex samples with low analyte concentrations. Biological samples (urine, blood, plasma, cerebral spinal fluid, tissue etc. READ MORE

  7. 25. Novel on-line mid infrared detection strategies in capillary electrophoretic systems

    Author : Malin Kölhed; Bo Karlberg; Sven P. Jacobsson; Andre' J. Sommer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; on-line hyphenation; mid infrared detection; capillary electrophoresis; FTIR; quantum cascade laser; aqueous samples; Analytical chemistry; Analytisk kemi;

    Abstract : Infrared absorption spectra can provide analytically useful information on a large variety of compounds, ranging from small ions to large biological molecules. In fact, all analytes that possess a dipole moment that changes during vibration are infrared-active. The infrared (IR) spectrum can be subdivided into far-, mid- and near- regions. READ MORE
