  2. 1. Electrifying the Molecules of Life : Peptide and Protein Analysis by Capillary Electrophoresis Coupled to Electrospray Ionization Mass Spectrometry

    Author : Magnus Wetterhall; Jonas Bergquist; Karin E. Markides; Dominic M. Desiderio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Capillary electrophoresis CE ; Electrospray ionization ESI ; Mass spectrometry MS ; Peptides; Proteins; Cerebrospinal fluid CSF ; Graphite coating; Monomer coating; Polymer coating; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis describes the current status and novel aspects of the analysis of the molecules of life, i.e. peptides and proteins, using capillary electrophoresis (CE) coupled to mass spectrometry (MS) via (sheathless) electrospray ionization (ESI). Early reports of sheathless CE-ESI-MS were plagued by limited lifetimes of the electrospray emitter. READ MORE

  4. 2. Separation of Pharmaceuticals by Capillary Electrophoresis using Partial Filling and Multiple-injections

    Author : Henrik Lodén; Curt Pettersson; Torbjörn Arvidsson; Ahmad Amini; Morgan Stefansson; Uppsala universitet; []
    Keywords : Capillary Coating; Chiral Separation; Enantiomers; Mass-spectrometric Detection; Method Validation; Multiple-injection Capillary Zone Electrophoresis; Non-aqueous Capillary Electrophoresis; Organic Solvents; Pharmaceutical Analysis; Quantitative Analysis;

    Abstract : Different multiple-injection methodologies and the partial filling technique (PFT) have been utilized for separation of pharmaceuticals by capillary elec-trophoresis. In multiple-injection capillary zone electrophoresis (MICZE), the samples and all standards, used for construction of the calibration curve, are analyzed within a single run. READ MORE

  5. 3. 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

  6. 4. Variations Related to Print Mottle in Starch-Containing Paper Coatings

    Author : Micael Ragnarsson; Lars Järnström; Gunnar Engström; Martti Toivakka; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pigment coating; porosity variations; coating structure; coat weight variations; starch; dextrin; CMC; latex; print mottle; calendering; pilot coating; offset printing; Chemical Engineering; Kemiteknik;

    Abstract : Starch in paper coatings is known to increase the risk of print mottle in lithographic offset printing. The objective of this study was to increase the understanding of this behaviour. READ MORE

  7. 5. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

    Author : Sven Lohmander; KTH; []
    Keywords : aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

    Abstract : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). READ MORE
