Abstract:
A system for measuring gas transport in a fluid sample, the system comprising:a temperature-controlled environment;a dispenser disposed within the temperature-controlled environment for dispensing the fluid sample at a predetermined flow rate;a gas-tight exchange chamber disposed within the temperature-controlled environment;a permeable artificial capillary disposed within the exchange chamber and having a first end in fluid connection with the dispenser for receiving the fluid sample, the artificial capillary being adapted to permit gas exchange between the fluid sample within the artificial capillary and an interior of the exchange chamber;an exchange gas supply adapted for providing a constant flow of an exchange gas to the exchange chamber;a sample collector in fluid communication with a second end of the artificial capillary for receiving an effluent fluid sample; anda gas analyzer for determining an amount of gas remaining in the effluent fluid sample.
