  1. 11. Knowledge retention and reuse : supporting engineering decisions in simulation-driven product development

    Författare :Michael Lundin; Martin Helgoson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Information exchange is becoming more and more important as modern manufacturers increasingly rely on integrated product development. Research shows that designers may not be aware of existing information or be willing to disrupt their work to search for the relevant information. LÄS MER

  5. 14. Retention time predictions in Gas Chromatography

    Författare :Yasar Thewalim; Anders Colmsjö; Torgny Fornstedt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; computer simulation; two-parameter model; retention time prediction; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : In gas chromatography, analytes are separated by differences in their partition between a mobile phase and a stationary phase. Temperature-program, column dimensions, stationary and mobile phases, and flow rate are all parameters that can affect the quality of the separation in gas chromatography. LÄS MER

  7. 15. Investigations of the retention mechanisms in hydrophilic interaction chromatography

    Författare :Ngoc Phuoc Dinh; Knut Irgum; Andrew J. Alpert; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HILIC; hydrophilic interaction chromatography; adsorption isotherm; water enriched layer; multivariate data analysis; retention mechanism; separation; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Hydrophilic interaction chromatography is well known as a powerful technique separation of polar and ionizable compound nowadays. However the retention mechanism of the technique is still under debate. Understanding retention mechanism would facilitate the method development using the technique and its future improvement.
