    Determination of carbon disulphide in air as xanthogenate by ion chromatography and capillary electrophoresis (1999)
    Springer
    Chromatographia 49 (1999), S. 678-680

    Notes: Summary A simple and sensitive method is presented for the measurement of carbon disulphide in air without interference from other gaseous sulphides. The procedure is based on the collection of CS2 in an ethanolic solution of KOH, where it is converted to potassium ethyl xanthogenate (PEX). The latter is determined by high-performance ion chromatography (HPIC) and/or capillary zone electrophoresis (CZE). Laboratory and field determination of detection limit, reproducibility and linearity, and specific advantages over other gas chromatographic and wet chemical methods, are discussed. Quantitative measurements of CS2 in air can be performed after sampling for 1 h with limits of detection as low as 15 ppb by HPIC and ca 0.1 ppm by CZE.

    Evaluation of graphitized glass capillary columns (1978)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 1 (1978), S. 143-148 
    Details
    ISSN: 0935-6304
    Keywords: Gas Chromatography ; Capillary glass ; Tailor-made by graphitized carbon black precoating ; Application to pesticides, terpenes, aromatic hydrocarbons, free fatty acids ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    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.
