Abstract

The use of the charcoal tube-gas chromatographic method to evaluate workplace air contamination has proliferated greatly in the las 10 years. This report documents early efforts by NIOSH researchers to evaluate several sampling and analytical parameters and their effect on the reliability of the technique. The effects of humidity, sample stability, sample migration and variations in the desorption efficiency are presented. A protocol is suggested for basic testing of the method for new substances.

摘要

在过去十年中，使用活性炭管-气相色谱法评估工作场所空气污染的情况已大幅增加。本报告记录了美国国家职业安全与健康研究所（NIOSH）研究人员早期为评估若干采样和分析参数及其对该技术可靠性的影响所做的努力。文中介绍了湿度、样品稳定性、样品迁移和解吸效率变化的影响。针对新物质的该方法基础测试，建议了一个方案。
