Development of on-line and field dual TD-GC-FID/MS for automatic and continuous Volatile Organic Compounds (VOCs) ambient air and odour monitoring
Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 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 ...
Experimental Determination of LOD for VOCs in Ambient Air Measured by Auto-GCs and Comparison with Reference Methods
Abstract Automatic gas chromatograph (auto-GCs) manufacturers perform an experimental method for a simple, rapid, and low-cost detection limit evaluation for volatile organic compounds in ambient air. The principle is the estimation of a minimum area of a peak. It is a relevant area value that discerns a real peak from the ground noise. This experimental limit of detection is equal to the minimum ...
