Tedlar Bag CE-5, CE - Standard sleeve (top) + M6 connector (top), 5 L

A Tedlar Bag (1L) was filled with nitrogen gas and put in an oven at 60 °C. 1 hour later, the gas in the bag was withdrawn into a gastight micro syringe and injected directly to a GC/MS. The bag was not flushed / cleaned in advance. 

After being filled with nitrogen gas, a Tedlar bag was closed and put in an oven at 60 °C. 1 hour later, 1L gas in the bag was vacuumed with a pump through a DNPH cartridge and eluted sample was analyzed by HPLC. These bag was not flushed / cleaned in advance. 

Vaporized standards as described below were introduced into Tedlar Bags. Then nitrogen gas was added into the Tedlar Bags and were measured by a GC/FID.

Standard Compound List: Acetone, Methylethylketone, Methyl isobutyl ketone, Isopropyl alcohol, Isobutyl alcohol, 1-Butanol, Ethylbenzene, Cyclohexane, n-Hexane, o-Xylene, m-Xylene, Toluene, Dicholoromethane, Methyl acetate, Ethyl acetate, Isobutyl acetate, n-Butyl acetate (50ng/mL each)

Each concentration of malodorous compound was prepared as described below and filled in a 5L Tedlar Bag together with nitrogen gas. Concentration changes over time were calculated with a detecting tube at certain times.

Permeation rate of O ₂ , N ₂ , CH ₄ and CO ₂ was measured using a permeation rate measurement system on Tedlar Bag. (in cm ³ /(m ²  • 24 h • 1 atm)
