Low adsorptionSampling bag

Low adsorption sampling bags (gas-phase consumables) can collect 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).

If containing ppm or ppb level active compounds, the sampling bag needs to be cleaned with high-purity air or high-purity nitrogen to reduce the influence of background. The sampling bag can also be placed in an oven and heated at 40 to 60 degrees Celsius to remove the influence of background.

Low adsorption sampling bags (gas-phase consumables) are suitable for using EPA analysis methods in the United States, including dissolution tests (TCLP), TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504, and various other atmospheric gas collection methods.

The main features are:

High transmittance, targeting ultraviolet and other rays, except for far-infrared radiation

High strength impact resistance, wear resistance, tear resistance

Superior anti adhesion and low friction properties

Easy to clean, reusable, and the basic composition and performance of the membrane material will not be affected

Resistance to dissolution and pollution, resistance to strong acids and bases (excluding molten alkali metals, fluorine gas, halogenated compounds at higher temperatures and pressures)

Low permeability to liquids, gases, moisture, and organic vapors

Cover the FEP film with an aluminum film to avoid light and prevent sample degradation.

The usage temperature of FEP sampling bags is -240 ° C to 205 ° C.
