- - 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 280/300C
- Baseline separation of Air, CO2, water, sulfur gases, hydrogen chlorine, ammonia/light amines from hydrocarbons 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 long lifetime 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 280C 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
