Emission testing

Qualitative and quantitative determination of volatile organic compounds from building products and indoor air

The following emission test chambers and analytical instruments are used to identify and quantify volatile organic compounds in indoor and test chamber air.

Emission test chambers:

Micro-chamber (µ-CTE)
Emission cell (FLEC)
23 L emission test chambers (glas)
1 m³ emission test chambers (stainless steel)

Analytical instruments:

Gas chromatograph and mass spectrometer with thermal desorption unit (TD-GC/MS)
Gas chromatograph and flame ionization detector with thermal desorption unit (TD-GC/FID)
Ion chromatograph (IC)
Ultra High Performance Liquid Chromatographie (UHPLC)
UV/Vis spectrometer
