FLEC Cell
The FLEC Cell (Field and Laboratory Emission Cell) is manufactured from acid-resistant stainless steel with polished internal surfaces. Its compact geometry minimises internal surface area and helps reduce sink effects compared with conventional chambers. The outlet design allows air to be collected on one or two sampling tubes while maintaining a small, constant overpressure in the cell. FLEC can be used for laboratory measurements, non-destructive testing on installed surfaces and production-line quality control, including wood flooring, paints and coatings.

How the measurement works
From surface emissions to laboratory results
The material closes the underside of the cell and defines the exposed surface. Controlled air carries released compounds to suitable sampling media. Analysis of the collected sample establishes which compounds were present and their concentrations.
- Prepare the specimenUse the appropriate holder and document the exposed area, material age and conditioning.
- Verify the flowsCheck the inlet flow and each sampling flow. Keep an excess-air path through the vent.
- Choose the analytical routeAgree sampling media, duration and analysis with the laboratory for the compounds of interest.
For VOCs, ISO 16000-6 describes sorbent-tube sampling followed by thermal desorption and gas chromatography. ISO 16000-3:2026 covers active air sampling and analysis for formaldehyde and other carbonyl compounds. For acrolein, Annex A uses sorbent-tube sampling with thermal desorption and GC-MS because the DNPH method is not considered reliable for quantitative results. ISO 16000-3 addresses sampling and analysis; the emission-cell test method is covered by ISO 16000-10. Compare results using a consistent preparation, climate and sampling procedure.
