【摘要】 目的:建立工作场所空气中环己烷和甲基环己烷气相色谱同时测定方法。方法:采用活性炭管吸附工作场所空气中环己烷和甲基环己烷,经二硫化碳解吸后进样,2 m×4 mm的5%SE-30玻璃柱恒温分离,由FID检测。结果:环己烷和甲基环己烷的保留时间分别为2.514 min、3.609 min;线性范围分别为8μg/ml～389μg/ml8、μg/ml～385μg/ml;检出限分别为8μg/ml、8μg/ml;相关系数分别为0.99990、.9999。结论:该方法适合工作场所空气中环己烷和甲基环己烷的气相色谱同时测定。更多还原

【Abstract】 Objective:To establish a method for the simultaneous determination of Cyclohexane and Methyl Cyclohexane in the air of workplace by Gas chromatography.Methods:Cyclohexane and Methyl Cyclohexane in the air of workplace were collected with charcoal tube,then injected after being desorbed with carbon disulfide,through 5% SE-30 glass column(2 m×4 mm) with constant temperature,detected by FID.Results:Retention time of Cyclohexane and Methyl Cyclohexane were 2.514 min,3.609 min.The linearity ranges were 8 μg/ml～389 μg/ml,8 μg/ml～385 μg/ml.The limits of detection were both 8 μg/ml.The coefficient of correlation were 0.9999,0.9999.Conclusion:The method is suitable to determine Cyclohexane and Methyl Cyclohexane in the air of workplace simultaneously.更多还原
