Automotive manufacturing, electronics, petrochemicals, environmental protection, research institutes, etc.

Tedlar? What gases can be collected by the sampling bag?

Carbon monoxide (CO), sulfur dioxide (SO2), hydrogen sulfide (H2S), benzene, radon and thiols, hydrocarbons, and chlorinated solvent gases. Suitable for short-term storage of low concentration (ppm, ppb level) corrosive gases and chemically active gases (for pre saturation treatment).
Collection of photosensitive compounds and halogenated volatile organic compounds (VOCs). Can it be in Tedlar? A layer of aluminum film is wrapped around the film material to avoid light and prevent sample degradation.

Tedlar? What laboratory analysis methods are suitable for gas sampling bags?

Tedlar? The gas sampling bag is suitable for using EPA analysis methods in the United States, including dissolution test (TCLP), TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504, and various other atmospheric gas collection methods.

Tedlar? What is the operating temperature of the sampling bag?

-20 degrees Celsius to+110 degrees Celsius

Tedlar? Reuse of sampling bags?

If containing ppm or ppb level active compounds, high-purity air or high-purity nitrogen should be used for cleaning to reduce the influence of background.
It can also be heated in an oven at+40 ° C to+60 ° C to remove the influence of background.

Injection or sampling method:

1. Silicone pad injection or sampling: a high elasticity pad used for needle sampling or vacuuming. After the needle is pulled out, immediately pinch the sampling pad slightly to facilitate the closure of the puncture site and ensure airtightness. (After multiple samplings, the sampling pad should be replaced)

2. Sampling with silicone or latex tubing: Take samples directly from the silicone or latex tubing. When there are too many needle holes inserted into the hose, a small section can be cut off, which is more convenient than sampling with a sampling pad.

Product Description:

1. Suitable for temperatures ranging from -20 to 110 ℃.

2. The lateral plastic valve switch is convenient and tightly sealed. A silicone gasket is installed inside the valve cap, and a needle can be used for sampling through the sampling hole. The air duct can be filled, deflated, and vacuumed. The interface can be connected to instruments and equipment through latex or silicone tubing.

3. The inflation pressure should not exceed 3KPa, visually indicating that the airbag is fully inflated, but it is not tight when pressed with fingers. Overpressure filling can cause gas sampling bags to burst and be damaged.

4. When storing and using, keep away from sources of fire and high temperatures, and avoid piercing with sharp objects.

When filling standard gas or sampling, it is advisable to replace it with pre installed gas three times. It is more convenient to replace it with a double-sided plastic valve.

6. If the gas sampling bag is reused, it should be replaced and cleaned multiple times.
