The hydrocarbon kicker removes hydrocarbons from the gas stream while
leaving the SO
permeation principle using differential pressure to force hydrocarbon
molecules to pass through the tube wall. The differential pressure is created
across the tube wall as sample gas passes through a capillary tube which
reduces its pressure. The sample gas is then fed to the shell side of the
hydrocarbon kicker. The kicker may be optionally mounted to the bench
to provide heating.
The optics section provides the light source for the fluorescence reaction

and optimizes the reaction with a system of lenses and mirrors. It includes a
flash lamp, condensing lens, mirror assembly, relay lens, and light baffle.
