Burner assembly

20
The burner assembly mounts on top of the GC in a detector
location, and contains the column connection.
For the SCD, the burner provides two heated zones, one at the
base and one farther up the assembly. In the burner base region,
the column effluent mixes with the lower hydrogen flow and air
or oxygen at high temperature. The resulting hydrogen flame
combusts the effluent. Low concentration components burn to
form the usual combustion products, including SO
compounds containing sulfur. The products are drawn upward
through a ceramic tube, where at even higher temperature the
upper hydrogen flow mixes with the combustion products,
causing the SO to reduce into SO.
