Sampling on solid adsorbents followed by thermal desorption and gas chromatography was evaluated as a simple method for the quantitative analysis of dimethyl sulphate, diethyl sulphate and ethylene oxide in the workplace environment. Tenax TA and Carbosieve S-III (for ethylene oxide) were found to be suitable adsorbents. The charged tubes can be stored at 22 degrees C for 4 days. The recovery is better than 98% (greater than 80% for ethylene oxide) in the mass range 1 ng-1 micrograms. The recovery is not dependent on air humidity. The limits of detection tested were at the lower parts per billion level.
对基于固体吸附剂采样、热脱附及气相色谱法进行评估，以作为 workplace environment 中硫酸二甲酯、硫酸二乙酯和环氧乙烷定量分析的一种简单方法。发现 Tenax TA 和 Carbosieve S-III（用于环氧乙烷）是合适的吸附剂。填充管可在 22 摄氏度下储存 4 天。在 1 纳克至 1 微克的质量范围内，回收率优于 98%（环氧乙烷大于 80%）。回收率不依赖于空气湿度。所测试的检测限处于十亿分率的较低水平。
