Continuous determination of volatile organic compounds gained increased importance in the field of indoor air quality since short-term emission events need to be assessed. This paper shows two exemplary applications. First, the development of reference sources for the validation of emission test chamber measurements is often connected to non-steady-state measurements with rapid changes in the chamber air concentration. The testing of these new sources needs high-time resolved measurements that are advantageous compared to thermal desorption methods. Second, the sensory evaluation of products using emission test chambers gains importance due to changes in certification regulations. The time-related performance of odor standards in olfactometers can be assessed via PTR-MS even at comparatively large concentrations.
