Th-300b on line monitoring system of volatile organic compounds (VOCs) in atmospheric environment


  working principle



  The ambient air is collected by the sampling system and then enters the concentration system. Under ultra-low temperature conditions, volatile organic compounds in the atmosphere are frozen and captured in an empty capillary column; then the compounds are quickly heated and analyzed to make the compounds enter the GCMS analysis system; after being separated by chromatographic column, they are detected by FID and MS detector.



 Functional features



 Low temperature empty tube can capture trace VOCs in air, and the capture efficiency and desorption efficiency are higher than that of adsorbent. The detection limit of     the system is low and the repeatability is good;
   Dual channel detector allows dual channel resolution and simultaneous analysis of data;

  天虹TH-300B助力杭州G20峰会
  娱乐平台靠谱的有哪些_网盛棋牌_大富豪棋牌受国家环保部委托,派出TH-300B VOCs在线监测系统参加G20峰会长三角区域环境空气VOCs自动监测,负责上海淀山湖空气自动站,江苏宜兴市监测站空气自动站,安徽芜湖市监测站空气自动站三个站点的VOCs在线监测工作,圆满完成了各项任务;并配合专家进行盲样测试、现场考核及仪器空白等多项指标的评估工作。

  2015年9月至2016年8月,天虹公司用TH-300B系统离线对全国14个国家大气背景空气站VOCs进行定性、定量分析,累计定性检出97种各类VOCs。


  TH-300A污染源挥发性有机物在线监测系统

  工作原理


  仪器采用专用色谱柱组合、中心切割加反吹技术和氢火焰离子化检测器(FID)技术进行甲烷和非甲烷总烃的检测。样品采集到定量环后,切换进样阀,在载气的带动下分别进入色谱柱中分离。其中一路总烃进入FID检测器中得到,另外一路氧气和甲烷从PQ色谱柱中分离,进入5A色谱柱中,切换阀位置后烃类被反吹,甲烷进入FID检测器检测得到。


  功能特点


  ● 采用中心切割加反吹专利技术,符合标准《HJ/T38-1999》,直接测量甲烷和非甲烷总烃;
  ● 采用专用的色谱柱组合,样品180℃保温。30s内出峰,无残留,灵敏度高;
  ● 仪器具有开机自检功能,断气保护功能,短期自动重启功能和报警功能,保证系统安全和稳定性;
  ● FID检测器具有自动点火功能和宽量程输出,线性范围10-7;
  ● 使用自动电子流量控制技术(EPC)控制载气、空气和氢气,高精度(0.01psi),重复性和再现好;
  ● 核心部件均使用国际知名品牌,可靠性高,使用寿命长。
