1. A sample analysis cup assembly, comprising:

  • a cell body, comprising;

    a top end;

    a bottom end;

    a cell body wall extending axially from said top end to said bottom end;

    a transverse wall adjacent said top end, including a plurality of apertures extending therethrough;

    a hollow chamber defined between said top end and said bottom end of said cell body; and

    a raised portion on said transverse wall including a central aperture extending therethrough;

    a rotatable cap, comprising;

    a top surface;

    a bottom surface; and

    a series of apertures extending from said top surface through said bottom surface, said rotatable cap being structured to engage with said top end of said cell body and to rotate about the raised portion thereof, said series of apertures being selectively and rotatably alignable with said plurality of apertures of said transverse wall, thereby allowing control of the rate of release of a gas through said selectively aligned apertures upon purging said chamber with a gas through said central aperture; and

    a ring member structured to couple with said bottom end of said cell body.
