Several studies depicted the presence and outgasings of VOCs in new cars, which is commonly known as “new car smell“. Typical harmful compounds found in new car interiors are: acetaldehyde, acrolein, benzene, toluene, ethylbenzene, o-, m-, p-xylene and styrene, e.g. With its GC-IMS device
G.A.S. offers a novel solution for detection and quantification of VOC outgasings by the use of the combination of an automated analyte enrichment & desorption, gas chromatography (GC) and ion mobility spectrometry (IMS) combining excellent selectivity with extraordinary sensitivity (low/sub-ppb level) within one measuring device.
The developed system detects and quantifies all the afore-mentioned VOCs down to a concentration level of 5 ppb and lower, whereas the cycle time is ~15 minutes only. Furthermore, the system is able to characterize the fingerprint of a “new car smell” by the orthogonal and intrinsic 2-dimensional separation technique of GC-IMS technology.
