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

  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.

  ● It can be used for industrial hygiene and full analysis of toxic and harmful gases at work site
  ● It can be used for urban air quality monitoring, VOCs qualitative and quantitative analysis in key monitoring areas and plant boundaries
  ● It can be used for the third party inspection and testing institutions
  ● It can be used for emergency monitoring in case of sudden environmental pollution events (mobile)

  Real time collection and analysis of real-time monitoring VOCs and characteristic pollution gas emission data, using the effective data audit mechanism to audit the monitoring data, provide real and effective monitoring data for the environmental monitoring part, master the pollution emission status in real time, and provide data support and decision support for pollution reduction and total amount control.
  ● Real time monitoring data and curve
  ● The sampling and analysis status of historical samples can be queried
  ● Historical monitoring data report can be queried according to various combination conditions
  ● According to the existing historical monitoring data, the big data integration analysis is carried out, and the principal component and correlation analysis of the monitoring data are carried out
  ● It can monitor the operation of the instrument remotely
  ● Quality control data can be inquired

  天虹TH-300B助力杭州G20峰会
  武汉天虹环保产业股份有限公司受国家环保部委托，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

  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。

  ● 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。
