Key Features:
Ultra-Wide Carbon Range (C1 to C12): Uniquely capable of retaining and resolving light permanent gases (CO₂, CH₄) simultaneously with heavier alkanes up to C12, eliminating the need for multiple column setups.
Critical Isomer Separation: Provides baseline resolution of light hydrocarbon isomers (C1-C3), which is crucial for petrochemical process control and olefin purity analysis.
Sulfur & Oxygenate Tolerance: The inert DVB polymer phase actively retains and separates trace sulfur compounds (e.g., H₂S, mercaptans) and oxygenated organics (alcohols, ketones, ethers) without irreversible adsorption.
Permanent Gas Resolution: Perfectly retains and separates CO₂ and CO from air (O₂/N₂) and methane without the co-elution issues common in standard columns.
Moisture Tolerant & Robust: Highly cross-linked structure prevents swelling or degradation in the presence of water, allowing direct injection of humid gas streams.
