Volatile organic compound (VOC) emissions from solids and liquids

Determination of the amount of volatile organic compounds (VOC) released by solid or liquid samples.

The measurement is performed by placing the investigated sample in a chamber, through which nitrogen is flushed. The nitrogen is led through an absorption cartridge, which traps the VOC compounds. Upon completion of the gas collection, the trapped VOCs are analyzed with thermal desorption-gas chromatography (TD-GC).

The measurement can either be performed at ambient temperature, or the sampling chamber can be heated.
