Sampling Accessories: FLEC® Emission Cell
VOC emissions from materials
The Field and Laboratory Emission Cell (FLEC®) is used for testing VOC emissions from planar materials and coatings in compliance with international standard methods. It offers a low-cost and easy-to-use alternative to conventional, large scale emission chambers.
The FLEC® is widely used in product development, industrial quality control and in environmental monitoring for sources of indoor air pollution. Samples compatible with VOC emission testing using FLEC® include:
- Water-based paints
- Wood panel products
- Adhesives
- Flooring products
- Sealants
- Carpeting
- Ceiling tiles
Principles of operation
FLEC® is constructed of acid resisting stainless steel with a polished inner surface designed to eliminate sink effects. It is placed onto the material to be tested such that the surface of the material effectively becomes one wall of a mini test chamber. A controlled flow of purified and humidified air enters the cell and passes over the test material at flow rates simulating real-world conditions. Exhaust gases from FLEC® are typically collected in sorbent tubes and analysed using thermal desorption-gas chromatography/mass spectrometry (TD-GC(MS))technology as described in international standard methods.
Accessories and applications
A range of accessories are available to extend the application range of FLEC® technology. These include test plates for carpets, paints and coatings, rubber flooring etc.
Markes International is the only worldwide OEM distributor for FLEC® and is the exclusive UK & Ireland distributor. We are proud to promote and distribute the system worldwide.
