  2. 1. Interfacing HPLC with MALDI- and ESI-MS for Automated High Sensitivity Analysis of Proteins and Peptides

    Author : Tasso Miliotis; Lund Institutionen för kliniska vetenskaper; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; automated; phosphorylation; ZAP-70; peptides; proteins; comprehensive; multidimensional; two-dimensional; piezoelectric; microdispenser; flow-through; ESI-MS MS; Capillary HPLC; MALDI-TOF MS; Analytical chemistry; Analytisk kemi;

    Abstract : The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides.

  4. 2. Surface Sampling and Automated Liquid Membrane Extraction of Fungicides

    Author : Margareta Sandahl; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural water analysis; microporous membrane liquid-liquid extraction MMLLE ; supported liquid membrane SLM extraction; Dislodgeable fungicide residues; surface sampling; automated sample preparation for HPLC; Analytical chemistry; Analytisk kemi;

    Abstract : A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. READ MORE

  5. 3. Towards more selective sorbents for extraction of drugs and biomarkers from biological fluids using molecularly imprinted polymers

    Author : Mohammad Mahdi Moein; Mohamed Abdel-Rehim; Milton L. Lee; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted polymer; sol-gel; solid phase extraction; microextraction by packed sorbent; monolithic column; Analytical Chemistry; analytisk kemi;

    Abstract : Sample preparation has a critical role as a first step in analytical processes, especially in bioanalysis and environmental analysis. A good sample preparation technique should be robust and stable, regardless of the sample matrix. READ MORE
