技术介绍
随着工业的发展,城市内的空气质量越来越差,严重影响到人们的身体健康,为此,现在多采用空气检测装置对周围环境进行检测,并根据检测结果采取相应的手段,减少或净化空气。目前的空气检测装置包括空气采样器和分析仪两部分,其中,空气采样器是一种辅助仪器,能够对被检测环境空气中的被测气体污染物进行采集或提取,与气相色谱分析仪等仪器连用就可以检测出被检测环境空气中的气体污染物浓度。现有的一种空气采样器包括吸附剂柱芯、过滤层、底座和外罩,其中吸附剂柱芯设置于中心位置处且与底座相连接,过滤层设置于吸附剂柱芯的外侧,外罩设置于过滤层的外侧,且过滤层和外罩均与底座相连接。但是,由于过滤层为多孔材料层,采样结束后,吸附于过滤层的气体分子会对吸附剂柱芯造成污染,而导致检测结果不准确。因此外罩内设置了隔板将外罩分隔为第一容腔和第二容腔,底座与外罩组合时,吸附剂柱芯位于第一容腔内,过滤层位于第二容腔内,从而防止过滤层污染吸附剂柱芯。在进行采样时,将外罩摘除,将底座静置在空气中,被测环境中的气体会经由过滤层与吸附 ...
