    The GC separation of C2-naphthalene isomers using cyclodextrins and crown ethers (1992)
    Springer
    Chromatographia 34 (1992), S. 163-165 
    Details
    ISSN: 1612-1112
    Keywords: Gas chromatography ; Cyclodextrins ; Crown ethers ; Dimethylnaphthalene isomer
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The twelve structural C2 isomers of naphthalene are resolved on a single capillary column using α, β, or γ cyclodextrin as the stationary phase. A change in elution order is seen upon going from α to β and then γ cyclodextrin which can be related to the size of the cyclodextrin cavity and the stereochemical fit of the isomer. A crown-ether column and a liquid-crystal column were found to be unable to separate all of the isomers.

    The separation of hydrogen and deuterium homologues by inclusion gas chromatography (1992)
    Springer
    Chromatographia 34 (1992), S. 457-460 
    Details
    ISSN: 1612-1112
    Keywords: Inclusion gas chromatography ; Hydrogen/deuterium homologues ; Crown ethers ; Cyclodextrins
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Two types of inclusion complex forming compounds, crown ethers and cyclodextrins, were investigated for their ability to separate hydrogen and deuterium homologues. A number of different crown ethers, 15-crown-5, 18-crown-6 and 24-crown-8, as well as examples of α, β and γ cyclodextrins were evaluated with ten homologues. The size of the inclusion cavity was found to be the major factor affecting separation although other factors such as cavity environment and cyclodextrin ring substituents also play a role in the separation process.
