Tedlar Bag Tedlar Sampling Bag

Tedlar BAG Tedlar Bag

Tedlar BAG is made of polytetrafluoroethylene film.

● Operating temperature upper limit: 100 ℃

● Film thickness: 50 μ m

Application: Inorganic gases, organic solvents, etc.

Tedlar bags are suitable for various compounds ranging from permanent gases to organic solvent gases, but there are some issues. For example, the following figure shows the permeability measurements of O2, N2, CH4, and CO2 using the permeability measurement system (LYSSY GPM-250) on Tedlar Bag. According to this result, the permeability of CO2 is much higher than that of CH4 and N2. This trend can be observed in organic solvent gases, where butanol and butyl acetate have high permeability. Therefore, depending on the composition of the sample gas, Tedra bags may not always be optimal.

Clean the Tedra sampling bag

Due to its high cost-effectiveness and ease of use, Tedlar bags are often used for the sampling bag method to determine volatile organic compounds in automotive interior materials. However, since the bag itself is made of raw materials such as N, N-dimethylacetamide, phenol, etc., the inside of the bag needs to be cleaned before use. The cleaning method requires a lot of time and cost, as it involves encapsulating nitrogen, heating for a long time, and then removing the nitrogen from the bag several times. To this end, we have launched a clean Tedler bag that greatly reduces the composition of the blank. The cleaned Tedler bag has strong measurement capabilities for the use of sample collection bags, such as sampling bag method, work environment measurement, analysis of odor substances, and measurement of VOC emission control systems
