  • Title: [Gas chromatography determination of trichloroethylene and tetrachloroethylene in the air].
    Author: Krajewski J, Dobecki M, Czerczak S.
    Journal: Med Pr; 1977; 28(2):129-34. PubMed ID: 865274.
    Abstract:
    Parameters of gas chromatographic separation and determination of trichloroethylene and tetrachlorethylene have been elaborated. The best separation has been achieved on column containing 7% OV-17 on Chromosorb W AW DMCS. For air samples collection, a method of absorption on charcoal and consequent desorption with carbon disulfide has been adapted. Stability of concentration of determined compounds in gas pipettes has been also evaluated. The investigations proved the concentration of compounds in gas pipettes to decrease in time. The magnitude of decrease was dependent on initial concentration and the boiling points of the compounds.
