Agilent, G3591-81003, J&W GC packed column in UltiMetal tubing, length 10 ft (3.05 M), 1/8 in. OD, 2 mm ID, MolSieve 13X packing, mesh size 45/60, pre-conditioned

Agilent J&W UltiMetal Molecular Sieve 13X is a preconditioned packed gas chromatography column designed for separations that require a molecular-sieve stationary packing. The column contains MolSieve 13X in a 45/60 mesh grade and is constructed with UltiMetal tubing. Packed-column geometry and adsorbent chemistry distinguish it from open-tubular capillary GC columns used for organic analyte partitioning. The 10 ft (3.05 m) column has a 1/8-inch outside diameter and 2 mm inside diameter. Molecular-sieve packing provides a selective adsorbent bed for suitable small gas components under established GC methods. Preconditioning makes the column ready for initial installation and system-specific equilibration, although instrument connection, carrier-gas flow, and operating temperature still require verification against the GC setup. Agilent's packed-column selection information specifies a 400 °C maximum temperature for this dimension and packing configuration. Choose this column when the intended method calls for MolSieve 13X and the instrument accepts the packed tubing dimensions, rather than substituting a capillary phase with the same length.
