A monouse Fe/C alloy cylinder containing liquified
C4H10 feeds liquid & gas through a highly flexible
plasticized vinyl conduit to a Cu/Zn alloy port on a polyvinyl
chloride chamber formed from standard prethreaded versatile construction units.
The chamber is immersed in liquid N2 stabilized via evaporation at its
liquid/gas phase transition point at 760T and 77K, with a high thermal barrier to
ambient conditions provided by an evacuated-wall vessel.
In this chamber the fluid is brought below its solidification temperature of 135K, and so forms a plug.
The intent is that the chamber can then be disassembled to gain access to the
plug, which will be retrieved and subjected to first-order pyrolytic analysis.
