  • What is a volatile organic compound (VOC)?

    Volatile organic compounds (VOCs) include a wide range of both natural and synthetic substances. VOCs are chemical compounds – mixtures of more than one element – where one of the elements is carbon. They are described as volatile because they evaporate easily, releasing molecules into the atmosphere. VOCs ...

  • Factors affecting the choice of VOC sensor

    VOCs (Volatile Organic Compounds) perform many vital roles as fuels, solvents, cleaners, feedstock, sterilants etc. However, they can be harmful to health and the environment, so it is often necessary to monitor their concentration. By definition, organic compounds contain the element carbon, and exhibit similar chemical properties, which is advantageous from a monitoring perspective. However, ...

  • Development of on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Ambient air is polluted by many semi-Volatile and Volatile Organic Compounds (SVOCs and VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from pg/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform ...

  • Effects of high humidity on photoionisation detectors (PIDs)

    There are a few important issues to look out for when choosing an instrument. Like many sensors and measurement instrumentation, traditional PIDs can be affected by the adverse environmental conditions such as those found at fire scenes i.e. dirt, water and humidity. The situation in the immediate aftermath of a fire is therefore not ideal and in particular the presence of high humidity can ...
