An acid-treated Pittsburgh Activated Carbon (PAC) tube for sampling s-tetrachloroethane in air is described that minimizes sample losses through dehydrogenation and dehydrohalogenation reactions. Commercially prepared NIOSH characoal, untreated PAC, and acid-treated PAC tubes are compared as to their effectiveness in stabilizing s-tetrachloroethane. Common homologues and analogues of s-tetrachloroethane cause no interference with the gas chromatographic method. -n addition the effectiveness of the untreated PAC and acid-treated PAC tubes was also evaluated for four different chlorinated aliphatic hydrocarbons.
描述了一种用于采集空气中s-四氯乙烷的经酸处理的匹兹堡活性炭（PAC）管，该管可最大程度减少因脱氢和脱卤化氢反应造成的样品损失。对市售的美国国家职业安全与健康研究所（NIOSH）活性炭、未处理的PAC管和经酸处理的PAC管在稳定s-四氯乙烷方面的有效性进行了比较。s-四氯乙烷的常见同系物和类似物不会对气相色谱法造成干扰。此外，还评估了未处理的PAC管和经酸处理的PAC管对四种不同氯化脂肪烃的有效性。
