GC Packed Columns

ShinCarbon ST Columns

Analyzing the permanent gases oxygen, nitrogen, methane, carbon monoxide, and carbon dioxide has been virtually impossible for
a single gas chromatography (GC) or gas-solid chromatography (GSC) column, without sub-ambient temperatures.
ShinCarbon ST material, a high surface area carbon molecular sieve (~1500 m2/g), is the ideal medium for separating gases and
highly volatile compounds by GSC. A 2 m x 1 mm ID micropacked column containing ShinCarbon ST separates the permanent gases
in 10 minutes, without cryogenic cooling (Figure 1).
ShinCarbon ST columns can also separate light hydrocarbon / permanent gas mixtures. Figure 2 shows an analysis of permanent
gases plus acetylene, ethylene, and ethane, completed in less than 20 minutes. Natural gas components (70% methane) also
are cleanly separated (Figure 3). Other potential applications for ShinCarbon ST include analyses of sulfur dioxide and Freon®
fluorocarbons (Figure 4).*
* For analysis of other low molecular height sulfur compound, we recommand Rt-X2 Sulfur micropacked and packed columns or SH-Rtx-1 Capillary columns.
