An experimental study was conducted with particular focus on a new sealing technique which was found to provide fully gas-tight conditions with a 100% success rate for the 6 membranes reported in this work (and for 15 membranes in total).
Tight gas, shale gas, tight oil, and shale oil also have been sporadically produced from the Triassic Xujiahe and Jurassic Ziliujing Formations.
Unconventional oil and gas resources, such as tight gas, tight oil and shale oil, have been successfully developed commercially in the USA, Canada, Australia and some other countries.
Anaerobic growth of bacteria is performed in gas tight hungate tubes under Ar atmosphere.
The lid was equipped with three gas-tight electric ducts.
The fermentation gases were simultaneously collected in gas-tight bags (Plastigas, Linde AG, München, Germany).
Produced gas was sampled from one of the sampling loop ports using a gas-tight syringe for gas analysis injection.
The volume of biogas production was measured by a plunger displacement of gas-tight syringes [7].
The blood samples were collected in pre-heparinized plastic gas-tight syringe.
The experimental bath was sampled (100 µl) using gas-tight glass Hamilton syringes (Hamilton Company, Reno, NV).
Using gas-tight syringes (Hamilton, Reno, NV), 300 μL headspace gas was injected into the gas chromatograph.
