New car smell: Improved identification of odours in vehicle interior air
This study demonstrates the discovery of odour compounds using thermal desorption with GC×GC–TOF MS. This provides target and non-target screening of car trim components on a single platform, for advanced analysis of vehicle interior air quality (VIAQ).
The figure shows the TD–GC×GC–TOF MS colour plot for a section of the steering wheel cover with the typical target compounds – from regulated methods such as GB/T 27630 – annotated on the plot. Many of these target components would have co-eluted with numerous other compounds in the equivalent 1D separation, meaning that concentrations would likely be overestimated, or the target compounds could be missed completely.
