  1. 1. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

    Författare :Saioa Zorita; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted solid-phase extraction; Sample preparation; solid-phase extraction; membrane extraction; human pharmaceuticals; sewage treatment plant; steroid hormones;

    Sammanfattning : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks.

    Sammanfattning : 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. LÄS MER

  5. 4. Molecularly Imprinted Solid-Phase Extraction and Liquid Chromatography for Biological Samples

    Författare :Kristina Möller; Ulrika Nilsson; Maria Kempe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis focuses on the use of molecularly imprinted polymers as selective sorbents for solid-phase extraction (MISPE). The MISPE methods developed were mainly intended for use with biological samples, such as human urine and blood plasma. LÄS MER

  7. 5. High-throughput screening of solid-phase extraction materials using mass spectrometry

    Författare :Kishore Jagadeesan; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :mass spectromery; protein separation; sample preparation; Molecularly imprinted polymer; Data analysis; Data visualization; Miniaturisation; Proteomics;

    Sammanfattning : In biomarker analysis, sample preparation plays a crucial step in order to extract, isolate and concentrate the analytes of interest. Among the various sample preparation techniques, solid phase extraction (SPE) is one of the most common and popular, due to the high enrichment factor, good recovery, low consumption of organic solvents and the possibility to automate (off- or on-line) the whole process.
