Study on the quantitative evaluation method of SVOC in a vehicle cabin using the passive method

摘要

In order to lower vehicle interior VOC concentration, Japan Automobile Manufacturers Association (JAMA) is announced self-imposed control of vehicle interior VOC concentration. Although high boiling point substances, such as phthalate ester, are contained in the substances for self-imposed control, these quantity boiling point substances are difficult to measure with sufficient accuracy in the collection by the conventional tube (Tenax-TA). In this research, we studied the plate material suitable for adsorbing SVOC. Solvent extraction method was found to be suitable for desorption method of SVOC adsorbed on plate. Quartz plate was the best for SVOC adsorption performance on plate and desorption performance of SVOC adsorbed on plate. In the actual vehicle measurement, DOA and DEHP were able to detect more efficiently than conventional active sampling.
