The reaction mix was primed, and the tip containing the emulsions (with fluorinated oil evacuated by pushing the glass syringe until the emulsions reached the exit of the tip) was primed and connected to the device. The droplets were then re-injected in a pico-injector device and coalesced ...
The fluid is preferably provided to flood the sample chamber and lubricate the passageway for transport. In addition the fluid may be only sufficient to fill in the space behind the bulkhead or bulkheads so that they, and the tissue, move more freely without creating any vacuum, even ...
so that the tunable laser beam passes first through the reference gas in the chamber 28 and then through the sample gas in the chamber 30 where it is multiply reflected and returned back through the reference cell 28. A single pass absorption cell may also be utilized in combination with a...
The piston 46 is moved to the right to generate the vacuum by expanding the volume of chamber 45. Because the passage 10P is closed, the total volume evacuated, relative to the chamber volume 45, is markedly decreased. This configuration of passage 10P also has the advantage of avoiding ...
The apparatus was evacuated for 10 min by a mechanical pump (PU) to a pressure of ~20 Torr. After closing the pump inlet valve (V-21/V-44) the pressure inside a reaction flask was continuously recorded for 20 min by an electronic pressure gauge attached to a LabQuest 2 digital data ...
