    Notes: The performance of graphitized glass capillary columns obtained by precoating the inner glass walls with graphitized carbon black has been evaluated. It has been shown that according to the amount of stationary phase coated such columns can operate in gas-liquid-solid chromatography and in gas-liquid chromatography so that tailor-made columns for specific separations can be prepared. The versatility of these columns is shown in the separation of various mixtures (terpenes, pesticides, isomeric species and others) of analytical importance.

    Short capillary column for the separation and identification of mononitrofluoranthene and mononitropyrene isomers present in air and emission samples (1988)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 11 (1988), S. 306-312 
    Details
    ISSN: 0935-6304
    Keywords: Capillary GC ; Nitrofluoranthenes ; Nitropyrenes ; Diesel exhaust ; Urban particulate matter ; Industrial emission ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: A 15 m DB-17 fused-silica capillary column has been used to achieve the separation of all mononitrofluorarthene and mononitropyrene isomers. Linear Retention Indices and Relative Retention times for each component have been measured and the values were compared with those observed on DB-5 columns, commonly used for this separation. Increased polarity of the liquid phase results in better separation of some key isomeric pairs (such as 2-, 3-nitrofluoranthene and 1-nitropyrene, 8-nitrofluoranthene), difficult to resolve on DB-5 columns. Practical applications are reported. They include the analysis of extracts from emission samples (diesel exhaust and particles emitted by a factory manufacturing carbon electrodes) as well as atmospheric dust sampled in a urban area under different conditions.
