  1. 21. New Techniques for Chiral Separations

    Författare :Jeanette Olsson; Lars Blomberg; Steen Honoré Hansen; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; analytical chemistry; chiral separation; GC; CE; CEC; Analytical chemistry; Analytisk kemi; Kemi; Chemistry;

    Sammanfattning : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.
