  • Development of on-line and field dual TD-GC-FID/MS for automatic and continuous ambient air monitoring

    Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, T014 and T015 lists can be measured in many ranges of concentration, from ng/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 using chromatographic ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • DOAS Explained

    DOAS stands for Differential Optical Absorption Spectroscopy. The DOAS technique was conceived almost a century ago, and it was applied on research level to air quality monitoring already in the 1970s. In the mid-1980s, the technology was then commercialised and turned into practical and wide-spread use. ...

  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...
