Our automotive odour testing is thorough and comprehensive. We will evaluate the whole vehicle interior, to determine the overall odour character of the vehicle.

Images of the sampling: sample closes to exhaust conduct (left) and close to the mirror (right).
The predominant families in the samples are aliphatic hydrocarbons, aromatic compounds, cyclic hydrocarbons, ketones and alcohols (Figure 2). Some odour relevant compounds in the second-hand car were the octanal aldehyde, and the organic acid butanoic acid, 3-methyl-.
These compounds are responsible for citrus, fatty and green odour notes and cheese, sweat and rancid for the organic acid.
The new car had hexanal aldehyde as a relevant compound and generates odour notes of grass, green and fresh.
