Vehicle Interior Air Quality
What is VIAQ Analysis and why does it matter?
There is a growing interest in VIAQ analysis, or vehicle interior air quality analysis. Various vehicle trim components, including PVC, polyurethane, foam, carpets, and adhesives emit volatile organic compounds or “VOCs” into the air. These can have negative impact on the comfort and health of drivers and passengers. Often, this aroma is referred to as the “new car smell”.
The health impacts of VOCs in the vehicle interior have led several countries to impose limits and regulations on the concentrations of VOCs emitted from newly manufactured vehicles. This has been reflected in the development of harmonized methods to quantitate releases of chemicals released from the materials used, and assess the overall quality of in-vehicle air.
Using these methods, the emission levels and potential impact of any given car trim component can be evaluated. Levels of volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and specific malodorous compounds emitted under different conditions can be determined.
Two key solutions for VIAQ analysis are selected ion flow tube mass spectrometry (SIFT-MS) and thermal desorption (TD) in conjunction with GC/MS:
SIFT-MS (Selected Ion Flow Tube Mass Spectrometry)
SIFT-MS is a new technology that can be deployed to analyze Vehicle Interior Air Quality and exhaust emissions in real time at parts per trillion (ppt) levels. Discover why the the SIFT-MS from Syft Technologies is an ideal instrument for testing chemically diverse VOCs in a VIAQ application.
Thermal Desorption with GC/MS
Using thermal desorption (TD) in conjunction with GC/MS can analyze potentially harmful volatile organic compounds (VOC) in vehicle interior air. By coupling Markes’ UNITY-xr and TD100-xr thermal desorbers and related sampling methods, analysts determine and quantify the compounds affecting VIAQ.
