    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical Fluid Chromatography; Mass Spectrometry; Ionization; POPs; APPI; APCI; chiral; achiral; packed column;

    Sammanfattning : Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). There are also a small number of compounds which are not easily amenable to either of these traditional separation techniques. LÄS MER

  4. 3. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC
