。Divinylbenzene polymer particle, nonpolar, close to traditional PoraPak Q
。Truly immobilized coating and smooth baseline workable for valve switching and liquid sample introduction at low temperatures
。Highest temperature limit, upto 280/300
。Baseline separation of Air, CO2, water, sulfur gases, hydrogen chlorine, ammonia/light amines from hydrocar bons such as refinery
　 stream, natural gas, and engine exhaust
。Excellent separation of C1 to C3 isomers, good separations of C3 to C12, halocarbons
。Excellent inertness and stability of water/alcohol sample, a good secondary choice of wax column for alcohol analysis
。Excellent tolerance to strong acid/base sample without affecting retention time
。Good anti-oxidation at 280?? and fast regeneration of performance
。Observed slight sulfur gas, hydrogen chlorine, and amine absorption
。Water peak is tailing, but no effect on retention
。Good choice for analyzing low level solvent residues from wide samples, such as headspace, aqueous, or organic solutions
。Preferred column for residue analysis in petroleum industry, pharmaceutical, environmental, chemical weapon detection
。Preferred column to analyze polar compounds including oxygenates from hydrocarbon streams: natural gas, refinery gas, dienes,
　 ethylene, propylene
