A novel method for monitoring occupational exposure to ethylene oxide was developed. Ethylene oxide was collected on Columbia JXC activated carbon, desorbed with carbon disulfide, and analyzed by gas chromatography using a TERGITOL TMN or UCON LB55OX column. Several parameters such as selection of adsorbent and column; effects of humidity, sampling rate and volume; shelf-life; interference from ten contaminants; desorption technique and calibration curve were investigated. The lower detection limit of the method is 0.15 ppm in ten liters of air. The method was evaluated statistically and by conducting a round-robin interlaboratory study.
开发了一种监测职业性环氧乙烷暴露的新方法。环氧乙烷采集于哥伦比亚JXC活性炭上，用二硫化碳解吸，并用气相色谱法，使用TERGITOL TMN或UCON LB55OX柱进行分析。研究了吸附剂和柱的选择、湿度、采样率和体积的影响、保质期、十种污染物的干扰、解吸技术和校准曲线等几个参数。该方法在十升空气中的最低检测限为0.15 ppm。通过统计评估和进行实验室间循环研究对该方法进行了评估。
