MXT-Msieve 5A Metal PLOT Column, 30 m, 0.53 mm ID, 50 µm, 7″ Diameter 11-Pin Cage

Restek’s molecular sieve 5A PLOT columns are designed for efficient separation of argon/oxygen and other permanent gases, including carbon monoxide. 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. Our deactivation technology also allows carbon monoxide to elute as a sharp peak. Additionally, our unique immobilization process guarantees that the uniform particles remain adhered to the tubing—even after continuous valve cycling.

Because molecular sieve materials are very hydrophilic, they will adsorb water from the sample or carrier gas. Water contamination can have a detrimental effect on peak symmetry and can reduce the resolution of all compounds. If water contamination occurs, reactivate your Restek Msieve 5A PLOT column by conditioning at 300 °C with dry carrier gas flow for 3 hours.

*We do not recommend recoiling PLOT columns as this may cause particles to dislodge from the side of the tubing.
