。Divinylbenzene and Ethylene glycol dimethacrylate copolymer particle, polar, close to traditional PoraPack U
。Truly immobilized coating and smooth baseline workable for valve switching and liquid sample introduction at low temperatures
。Improved separation and selectivity of Air, CO2, water, sulfur gases, hydrogen chlorine, ammonia/light amines from hydrocarbons
。Symmetric water peak shape, water elute after C3
。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
。Observed slight sulfur gas, hydrogen chlorine, and amine absorption
。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
