Analyses of Permanent Gases, Light Hydrocarbons, and Light Polar Compounds, Using Packed Column GC
GC columns containing Carboxen-1000 packing separate mixtures of permanent gases (nitrogen, hydrogen, oxygen/argon, carbon monoxide, carbon dioxide) and C1-C3 light hydrocarbons (methane, acetylene, ethylene, ethane, propyne, propylene, and propane). A 15’ x 1/8” column will separate the permanent gases and C1 and C2 hydrocarbons in less than 25 minutes. A 2’ x 1/8” column provides excellent resolution of the C1-C3 hydrocarbons in the absence of permanent gases. These one column analyses are more convenient than the two-column procedures often used to separate permanent gas/light hydrocarbon mixtures.
