Teflon gas sampling bags

Tedlar (r) is a high-quality thermoplastic gas sampling bag material used for VOC testing, fuel emission testing, chemical sampling, and breath collection. It is robust and durable, chemically inert, and abrasion-resistant.

It offers exceptional reusability and can store air samples for up to 6 or 7 days. However, the recovery of volatiles in bags filled to 80% of their nominal volume strongly depends on the polymer surface-to-volume ratio (SA:V).

Polyvinyl Fluoride (PVF) Film

Polyvinyl fluoride (PVF) film is a type of fluoropolymer used for many applications. It has excellent resistance to sunlight degradation, chemical attack, and water absorption, and is also a strong material that resists thermal damage.

In addition, PVF has a very low permeability to air and water, making it an ideal choice for a wide variety of applications. For example, it is a common protective coating for the exteriors of buildings and aircraft.

Tedlar PVF is a commercially available fluoropolymer that is trademarked by DuPont and has been in use for over 50 years. It is a clear, biaxially oriented polymer that can be shaped easily and lasts a long time, making a long-lasting finish.

These gas sample bags have a very low VOC and sulfur background, and they are very stable for most hydrocarbons, methane, and carbon dioxide. They are not as stable as hydrogen sulfide and some sulfur compounds, so they should be analyzed within 24 hours of collection.
