  1. 21. Development of analytical methods for determination of drugs, used against tropical diseases, in biological fluids

    Författare :Mikaela Malm; Högskolan Dalarna; []
    Nyckelord :;

    Sammanfattning : The overall aim of this thesis was to develop analytical methods for determination of drugs, used against tropical diseases, in biological fluids. For the treatment of malaria, piperaquine (PQ) is used in combination with another antimalarial. LÄS MER

  3. 22. Losing track of time : causes and solutions for the problematic determination of Baltic cod age

    Författare :Yvette Heimbrand; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Age is a fundamental parameter in biology and fishery science to estimate growth and population parameters. Losing track of time, in the sense of lacking reliable estimates of age and growth creates substantial problems for managing difficult-to-age-species. This thesis explores the use of fish otolith chemistry to improve age determination. LÄS MER

  4. 23. Development of Methods for Determination of Fat and Trace Constituents in Food, with Emphasis on Supercritical Fluid Extraction

    Författare :Hans Berg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid extraction; Steroids; SFE; Sample preparation; Meat; Lipid classes; Food; Fatty acid composition; Fat content; 3-butanediol; 2; Diacetyl; Acetoin; Androstenone; vitamins A and E.; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Sample preparation is the most time-consuming step in an analysis. Traditional sample preparation techniques consume large amounts of organic solvents, are time-consuming and are difficult to automate. LÄS MER

  5. 24. Analysis of 3D surface data for on-line determination of the size distribution of iron ore pellet piles on conveyor belt

    Författare :Tobias Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet's sizes are critical to the efficiency of the blast furnace process in the production of steel. LÄS MER

  7. 25. Multidetection and chemometrics in flow injection analysis

    Författare :Robert Tryzell; Elo H. Hansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : An ideal method for the determination of ions in aqueous solutions should be fast, inexpensive, simple, reliable and require small sample volumes. Flow Injection Analysis (FIA) is in many respects such an ideal method but it is too often limited to the determination of one analyte at a time. LÄS MER
