Smart Bag PA AAK-30, AAK - 6 mm sleeve with mini valve (single), 30 L

Each sampling bag (1L) was filled with nitrogen and put in an oven at 60 °C. 1 hour later, the each gas in the bags is withdrawn into a gas tight micro syringe and injected directly to a GC/MS. Both bags were not flushed/cleaned with nitrogen.

After being filled with nitrogen, both bags were closed and put in an oven at 60 °C. 1 hour later, each 1L gas in the bags was vacuumed with a pump through a DNPH cartridge and eluted sample was analyzed by HPLC. The both bags were not flushed/cleaned before the test.

The same volume with the same constitution of vaporized standards were introduced to each bag. Then nitrogen was added to each bag 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, Dichloromethane, Methyl acetate, Ethyl acetate, Isobutyl acetate, n-Butyl acetate (50 ng/mL each)

After preparation of each malodorous sample as described below, 5L Smart Bag PA and 5 L Tedlar Bag were filled with the sample together with nitrogen gas. Concentration changes over time were calculated with a detecting tube at certain times.

Permeation rates of O ₂ , N ₂ , CH ₄ and CO ₂ were measured using a permeation rate measurement system on each sampling bag.
