A new type of personal sampler for gases in air, originally reported from this laboratory, has been adapted to measurement of NO2. The sampler depends on the transfer of NO2 by diffusion to a triethanolamine coated collector at the sealed end of a tube; the open end of the tube is exposed to the test environment. The devices are accurate, light, simple to use and have very good shelf life before and after sampling.
本实验室最初报道的一种新型空气中气体个人采样器已被用于二氧化氮的测量。该采样器依靠二氧化氮通过扩散转移到管密封端涂有三乙醇胺的收集器上；管的开口端暴露于测试环境中。这些装置准确、轻便、使用简单，并且在采样前后具有很长的保质期。
