| 摘要: |
| 用活性碳管采样,二硫化碳解吸,FFAP宽口径毛细柱分离,FID检测器对工作场所中三氯乙烯、四氯乙烯、二氯乙烷进行测定,建立工作场所中三氯乙烯、四氯乙烯、二氯乙烷共存时的气相色谱测定方法。该方法线性范围为0.13~1298.4μg/ml,最低检出浓度为0.09~0.11mg/m3,解吸效率为91.5%~99.4%,相对标准偏差<5%。该方法灵敏度高、精密度与准确度好,在满足实验要求的前提下,可以缩短采样和分析时间。 |

| Abstract: |
| Establish a gas chromatography method with trichloroethylene、perchlorethylene、dichloroethane coexistence in the workplace.Solvents such as trichloroethylene、perchlorethylene、dichloroethane are sampled with the activated charcoal,parsed with carbon bisulfide,separated with FFAP wide aperture capillary column and mensurated the three constituents with FID detector.Linear limits of this methods:0.13~1298.4μg/ml,the lowest consistency:0.09~0.11mg/m~3,efficiency of parse:91.5%~99.4%,the coefficient of variation in sample determination ranged <5%.In the premise of meeting the requirements of the experiment,the methods with high-sensitivity,good precision and accuracy can shorten sampling and analysis time. |
