FEP Gas Sample Bags
for gas, odour, and emission sampling.
FEP gives the ultimate in low contamination and easy cleaning. This range of FEP gas bags is normally specified for odour sampling and applications where a very low ppm are involved.
- No contamination of gas sample
- Easily cleaned for re-use by gas flushing
- Very low permeation of gases through the wall of the bags
- Range of inert connectors for ease of use
- Wide range of sizes
- Special designs for unusual requirements
- Large capacity gas bag chambers
- Internal manifolds if required
The range of PTFE connectors offered suit most applications, however, we can also apply custom free issue connectors if required.
Multiple use FEP bags can have a Kapton reinforced weld to increase life, and larger multiple use bags are often specified with internal FEP scavenger pipes to ensure complete evacuation of gases before re-using the gas sample bag.
We were approached by UMIST to create a cuboid gas sampling chamber 3 metres x 5 metres from FEP 50 micron film.
The main problem we had to overcome was how to create a 3 dimensional corner profile and ensure the integrity of the welded seam.
To achieve this, we chose to support the FEP sample bag structure by using an external frame, which relieved the stress on the welded area.
By making the FEP bag section in two halves, UMIST are able to easily adjust the capacity of the chamber, by raising and lowering the height of the top section. Whereby giving them greater flexibility with only one chamber.
Adtech's chambers are bespoke to each customer, as the demands of room size, chamber capacity needed and external fittings vary for each application. Please contact our technical sales team to discuss your particular requirement.
