Calibration Gas for Volatile Organic Compounds (VOCs) Monitoring

Volatile organic compounds (VOCs) are involved in the photochemical reaction of ozone and particulate matter (PM2.5) in the atmospheric environment. They are the culprits of regional atmospheric ozone and PM2.5 pollution, as well as important precursors of urban haze and photochemical smog. Usually, VOCs are generally toxic and have a serious impact on human and ecosystem healthy.
  

In order to improve the quality of the environment, governments have developed a series of VOCs governance and monitoring systems and standards, based on this, our company developed a series of VOCs monitoring calibration gases. The stability and uncertainty of TO-14, TO-15, PAMS, 4 compositions of VOCs can reach the level of international similar products after comparing with the (Spectra (Linde)). The 43 components of TO-14 VOCs calibration gas has also been tested by the Chinese Institute of Metrology and obtained satisfactory results.

Volatile Organic Compounds (VOCs) Monitoring calibration gases listed as below, meanwhile other calibration gases can be customized as required by customers.
