摘　　要：气体样品的采集在环境监测领域是十分重要的,传统的气体样品采集不仅采样时间长、劳动强度大、采样半径小而且平行样精密度差,增加环境监测气体采集的工作难度。手持式气体采集器则在传统气体采集器的基础上,解决了传统气体采集繁琐、计量不准等诸多问题,为快速、准确地获得监测数据提供了坚实的基础。Gas sample collection in environmental monitoring field is very important, the traditional gas samples were not only sampling time is long, labor intensity and the sampling radius small and parallel precision is poor, increase sample collection work environment monitoring gas difficulty. Hand-held gas collector is in traditional gas collector on the basis of traditional gas collection, solved the tedious, measuring prohibit such problems, for fast and accurately acquire monitoring data provide the solid foundation.
