*Please add column instrument configuration suffix number to cat.# when
ordering. See page 143.
**This column set is for a valving system; therefore, packing material is filled to
ends of columns.
Special Columns for Unsaturated Light Hydrocarbons
• Faster separations of C1 to C4 hydrocarbons.
• Res-Sil® packing replaces Porasil materials.
n
-Octane on Res-Sil® C Packed Column
This packed column has unique selectivity for resolving unsatu-
rated light hydrocarbons (Figure 1).
OPN on Res-Sil® C Packed Column
This column separates the light hydrocarbons, and baseline
resolves
cis
-2-butene from 1,3-butadiene (Figure 2).
2abc Refinery Gas Column Set
This 3-column set is finely tuned to resolve light hydrocarbons.
When used in the proper valving system, it will elute C5+ hydro-
carbons ahead of C1 through C4 hydrocarbons. (Figure 3)
