Molecular sieve 5A PLOT columns are designed for efficient separation of argon/oxygen and other permanent gases, including CH₄, C₂H₆, and CO.

• Improve accuracy with sharp, symmetrical peaks for argon, oxygen, and carbon monoxide
• Easily separate permanent gases at temperatures above ambient
• PLOT technology reduces particle release, improving flow reproducibility and reducing downtime for maintenance
• Stable to 300 °C

Special coating and deactivation procedures ensure chromatographic efficiency and the integrity of the porous layer coating. Molecular sieves have very high retention, allowing separations of permanent gases at temperatures above ambient. Additionally, the unique immobilisation process guarantees that the uniform particles remain adhered to the tubing - even after continuous valve-cycling.
