【摘要】 介绍了EcoSys-p便携式质谱仪在无车日前后对交通干线环境空气中苯系物现场监测中的情况,同时该方法与经典的气相-质谱联机进行了对比试验,相对偏差≤25%,能够满足交通干线环境空气苯系物的现场监测要求。更多还原

【Abstract】 Monitoring method for BTEX pollution charateristics in ambient air at traffic road with portable mass spectrum around car free day was introduced.The comparison tests between portable mass spectrum and classical GC-MS showed the deviation is no more than 25%,so the method could request for monitoring the BTEX pollution charateristics in ambient air at traffic road on the spot.更多还原
