*Please add column instrument configuration suffix number to cat.#when
ordering. See page 143.
**This column set is for a valving system; therefore, packingmaterial is filled to
ends of columns.
SpecialColumns forUnsaturatedLightHydrocarbons
• Faster separations of C1 toC4hydrocarbons.
• Res-Sil®packing replaces Porasilmaterials.

-OctaneonRes-Sil®CPackedColumn
This packed columnhas unique selectivity for resolvingunsatu-
rated light hydrocarbons (Figure 1).
OPNonRes-Sil®CPackedColumn
This column separates the light hydrocarbons, and baseline
resolves
cis
-2-butene from1,3-butadiene (Figure 2).
2abcRefineryGasColumnSet
This 3-column set is finely tuned to resolve light hydrocarbons.
Whenused in theproper valving system, itwill eluteC5+hydro-
carbons aheadof C1 throughC4hydrocarbons. (Figure 3)
