    Direct enantiomer resolution of primary, secondary, and tertiary alcohols by gas chromatography on Chirasil-Val (1986)
    Springer
    Chromatographia 21 (1986), S. 503-508

    Notes: Summary Many enantiomeric pairs of alcohols (primary, secondary or tertiary) are resolved directly on persilylated glass capillary columns, coated with the chiral stationary phase L- or D-Chirasil-Val. Dependent on the chemical structure of the substrate, considerable resolution factors can be obtained, even with simple aliphatic alcohols. Thus, one strong attraction may be sufficient to produce significant chiral recognition. Enantiomeric purities of these alcohols can be determined with high accuracy and great ease.

    Enantiomer and diastereomer resolution of dipeptides by gas chromatography on chirasil-val (1987)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 10 (1987), S. 324-327 
    Details
    ISSN: 0935-6304
    Keywords: Gas chromatography, GC ; Fused silica and glass capillary columns ; Enantiomer and diastereomer resolution ; Chirasil-Val ; Dipeptides ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Several dipeptides have been separated into stereoisomers (enantiomers, diastereoisomers, sequential isomers) by GC on the chiral stationary phase Chirasil-Val. Sufficiently volatile N-TFA-dipeptide methyl esters have been formed by derivatization at ambient temperature, thus avoiding racemization (or epimerization, respectively), and peptide cleavage. This novel approach has proven particularly useful for the determination of stereoisomeric composition of dipeptides in biological fluids.
