    Ion Chromatography of Inorganic Anions on Graphitic Carbon as the Stationary Phase (2000)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 23 (2000), S. 590-594 
    Details
    ISSN: 0935-6304
    Keywords: Ion chromatography ; graphitic carbon stationary phases ; anions ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: ---Inorganic anions could be separated on porous graphitic carbon stationary phases in ion chromatography. Ion exchange between eluent anions and sample anions on the stationary phase was confirmed by the retention behavior and the possibility of indirect photometric detection. The elution order of anions was different from that observed for commercially available anion exchangers. Chloride, nitrate, and sulfate contained in tap water could be determined in 7 min.

    Separation and fluorescence enhancement of dansyl amino acids assisted by γ-cyclodextrin and bovine serum albumin as mobile phase additive in microcolumn liquid chromatography (1995)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Microcolumn Separations 7 (1995), S. 575-580

    Notes: The effects of γ-cyclodextrin and bovine serum albumin as mobile phase additives on fluorescence intensity and retention of dansyl amino acids (Dns-AAs) have been examined in microcolumn liquid chromatography. Polymercoated mixed-functional silica packings were employed for the separation column. The concentrations of the additives, acetonitrile, and buffer affected the signal intensity and retention of DNA-AAs. The use of the mobile phase additives improved the detection limits by a factor of as much as 7.4. © 1995 John Wiley & Sons, Inc.

    Retention behavior of aromatic hydrocarbons and dansylamino acids in reversed-phase liquid chromatography with cation-exchange-induced stationary phases (1995)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 18 (1995), S. 745-748

    Topics: Chemistry and Pharmacology
    Notes: The retention behavior of aromatic hydrocarbons and dansylamino acids on cation-exchangers modified with alkylammonium ions has been examined by microcolumn liquid chromatography. Several parameters affected the retention of analytes, involving concentration of the modifier in the mobile phase, its alkyl chain length and mobile phase composition. Stationary phases modified with a reagent having longer alkyl chains achieved better column efficiency.
