, in 10minutes, without
cryogenic cooling.
• Rapid separations of permanent gas / light hydrocarbonmixtures.
• Excellent compatibilitywithmost GC detectors—minimal bleed,
minimal baseline rise.
• Pre-conditioned, less than 30minutes to stabilize.

Above-Ambient Analyses of Permanent Gases
and Light Hydrocarbons
Analyzing the permanent gases oxygen, nitrogen, methane, carbonmonoxide, and carbon dioxide
has been virtually impossible for a single gas chromatography (GC) or gas-solid chromatography
(GSC) column, without sub-ambient temperatures.
Now, Restek's newShinCarbon STmaterial, a high surface area carbonmolecular sieve (~1500
m
2
/g), is the ideal medium for separating gases and highly volatile compounds by GSC. A 2-meter
by 1mm IDmicropacked column containing ShinCarbon ST separates the permanent gases in 10
minutes, without cryogenic cooling (Figure 1).
In addition to providing a breakthrough in analyses of permanent gases, ShinCarbon ST columns
can separate light hydrocarbon / permanent gasmixtures. Figure 2 shows an analysis of perma-
nent gases plus acetylene, ethylene, and ethane, completed in less than 20minutes. Natural gas
components (70%methane) also are cleanly separated (Figure 3). Other potential applications for
ShinCarbon ST include analyses of sulfur dioxide (Figure 4) and Freon
®
fluorocarbons (Figure 5).*
