Odor determination by means of the olfactometer

The method of odor determination by means of the olfactometer is based on the guidelines Richtlinien VDI3881, pages 1 to and VDI 3882, pages 1 and Measuring nrincinle  

The results are presented in odor units/m of neutral air and they are automat-ieally displayed as flie averaged data of the panel s evaluation. 

4 Example for odor determination for seiected materials Determination of odorant concentration in varnished furniture surfaces 

The odor potential of furniture is determined primarily by the applied varnishes although adhesives also play a minor role. Furniture varnishes may contain up to 80% solvents. The residual solvents remaining in the varnish thus determine the VOC and odorant concentration of furniture surfaces. 

After 48 h of storage time without an air exchange, air samples are taken in parallel for the determination of VOC emission by means of gas chromatograph and for determination of odor by the olfactometer. Subsequently, there is an air exchange of one air change per hour, and the slow-down curve of VOC and odorant concentration is determined.
