¡£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, ¡¡
