Abstract |
Description of a method for sampling and analysis of aniline, N,N-dimethylaniline, o-toluidine, 2,4-xylidine, p-anisidine, o-anisidine, and p-nitroaniline. Air is drawn by a personal sampling pump from a worker's breathing zone through a tube containing silica gel to collect any anilines present. In the laboratory each silica gel section is transferred to a glass-stoppered tube and desorbed with ethanol. An aliquot of this is analysed by gas chromatography to determine the amount of each aniline compound present. The sampling tube can be used for short-term sampling at 1,000cm3/min or for sampling up to 8h at 200cm3/min. Maximum interference effects of water vapour have been considered. Results of retention, desorption, storage, accuracy, and precision studies are presented. |
