A comparison of aromatic hydrocarbon measurements is reported for the CENICA supersite in the district of Iztapalapa during the Mexico City Metropolitan Area field experiment in April 2003 (MCMA 2003)...
将自主研发的低压进样系统与GC-FID法相结合,解决了低压样气难以抽取进样的技术难题,实现了对SUMMA采样罐内低压样气中CO、CH4的分析.罐内样气压强大于30kPa情况下,该进样装置能将待测低压气体提升至常压状态并完成进样过程.本系统采用3个六通阀、5Å分子筛与TDX-01双柱实现O2、CO、CH4的有效分离.通过对5分子筛柱的反吹去除杂质组份,既保持基线平稳,又可缩短分析周期,...
