Key Features:
Unmatched Permanent Gas Separation: The 5Å molecular sieve pore size selectively retains gases based on molecular size and polarity, ensuring crisp, symmetric peaks for O₂, N₂, CH₄, CO, and CO₂ (with proper configuration).
Critical Pair Resolution: Easily achieves baseline separation of the challenging Argon/Oxygen pair (at sub-ambient temperatures if required) and Hydrogen/Helium.
High-Resolution PLOT Technology: The uniform, mechanically stable porous layer maximizes surface area while minimizing flow resistance, ensuring fast analysis times and high sample throughput.
Broad Detector Compatibility: Optimized for use with Thermal Conductivity Detectors (TCD) and can be paired with Methanizers for FID detection of trace CO and CO₂.
