ABSTRACT:
A novel gas investigation apparatus is provided herein. Such gas investigation apparatus includes a hollow cylindrical transparent barrel having a lower inlet and an upper outlet. A plunger is slidably fitted in a leak-proof manner within the barrel. A gas inlet tube having a lower and upper inlet and outlet is provided within the plunger and extends along the longitudinal axis of the plunger. A longitudinally-extending, transparent heat transfer jacket surrounds the hollow, barrel. An upper valve is connected to the upper outlet of the barrel by means of a zero dead-space, butt-end connection. A selective entry is provided through the upper valve for admitting a study liquid or a tissue suspension into the barrel. A lower valve is connected to the lower inlet of the gas inlet tube by means of a zero dead-space, butt-end connection. An inlet conduit is provided for the selective introduction of test gas, or carrier gas, or flushing gas into the gas inlet tube through the lower valve. An inlet tube is provided for the selective introduction of a gas sample into the inlet conduit through the lower valve. An exit tube is connected to the upper valve by means of a zero dead-space, butt-end connection for leading gas exiting from the barrel to a mass spectrometer.
