A method has been developed for air sampling and laboratory analysis of vapors of seven aniline compounds: aniline, N,N-dimethylaniline, o-toluidine, 2,4-xylidine, panisidine, 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 analyzed by gas chromatography to determine the amount of each aniline compound present. The sampling tube can be used for short-term sampling at 1000 cm3/min or for sampling up to eight hours at 200 cm3/min. Maximum interference effects of water vapor have been considered. Results of retention, desorption, storage, accuracy, and precision studies are presented.
已开发出一种用于空气采样及对七种苯胺化合物蒸汽进行实验室分析的方法，这七种化合物分别是：苯胺、N,N-二甲基苯胺、邻甲苯胺、2,4-二甲基苯胺、对甲氧基苯胺、邻甲氧基苯胺和对硝基苯胺。通过个人采样泵从工人呼吸区域经装有硅胶的管子抽取空气，以收集存在的任何苯胺。在实验室中，将每个硅胶部分转移至带玻璃塞的试管中，并用乙醇解吸。取其一份 aliquots 用气相色谱法分析，以确定每种苯胺化合物的含量。采样管可用于以 1000 cm³/分钟的流量进行短期采样，或以 200 cm³/分钟的流量进行长达八小时的采样。已考虑了水蒸气的最大干扰影响。给出了保留、解吸、储存、准确性和精密度研究的结果。
