SIBATA SCIENTIFIC TECHNOLOGY Gas Collection Tube Carbon Beads Active (for ethylene oxide collection)

●This is a gas collection tube in which carbon beads are impregnated with hydrobromic acid, packed into a glass tube, and sealed. ●Ethylene oxide in the work environment is derivatized and collected as 2-bromoethanol. ●High-purity silica wool is used between the two packed layers, making it easy to remove during extraction. ●After collection, the glass tube is broken to remove the carbon beads inside, which are extracted with a toluene/acetonitrile mixed solvent and analyzed by GC/MS. ●Low blank. ●This is an ethylene oxide collection tube filled with synthetic activated carbon impregnated with hydrobromic acid, and complies with Work Environment Measurement Guidebook 3 (Specialized Chemical Substances).
Ethylene oxide collection
*This product has a shelf life of one year from the date of manufacture. The manufacturing date can be confirmed by the lot number printed on the outer box. *This product does not have a pre-cutting process. *After sampling, store the adsorption tube in a clean, dry, cool, dark place (0-10°C) until analysis. *Bromine gas may be generated from the adsorbent. If using a constant flow pump, we recommend installing a trap such as silica gel between this tube and the pump to protect the pump.
