  3. 2. Characterization of dissolved organic matter : An analytical challenge

    Författare :Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Jeffrey A. Hawkes; Jonathan Martin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Dissolved organic matter (DOM) is the prevalent form of organic carbon in most aquatic environments. It is an ultra-complex mixture that plays a crucial role in global carbon cycling. Despite its importance it is still poorly understood due to its extreme heterogeneity and intricacy. LÄS MER

  4. 3. Analytical Methods For Sports Drugs: Challenges and Approaches

    Författare :Hatem Elmongy; Magnus Ericsson; Leopold Ilag; Mikael Hedeland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sports Drugs; Doping in Sports; Steroids; LC-MS MS; Chiral analysis; high-resolution mass spectrometry; Sample preparation; Biological samples; solid phase extraction; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Drugs used to enhance human performance in sport competitions are prohibited by the world anti-doping association (WADA). Biological samples from athletes are continuously tested for adverse analytical findings regarding the identity and/or quantity of the banned substances. LÄS MER

  5. 4. New approaches to preparation of macroporous monoliths for use in liquid chromatography

    Författare :Anh Mai Nguyen; Knut Irgum; Tatiana B. Tennikova; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monolith; polycondensation; dissolution-precipitation; epoxy-amine; poly-amide; nylon; emulsion polymerization; characterization; protein separation; liquid chromatography; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    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

  7. 5. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices

    Författare :Nahid Amini; Gunnar Thorsén; Tuulia Hyötyläinen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sample preparation; SPE; RAM; GCB µ-trap; GCB disk; High temperature LC; LC MS; ESI; APCI; Matrix effects; LIT-MS; SALDI; Sample screening; Oxidized GCB; Silicon nitride; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. LÄS MER
