Answer:Molecular Sieve 13X adsorbent with 45/60-mesh particle size.
Answer:A 10 ft (3.05 m) preconditioned nickel packed column with 2 mm internal diameter and 1/8 in. outside diameter.
Answer:Water is strongly retained by molecular sieves and can change adsorption behavior, retention and separation performance.
The Agilent J&W Molecular Sieve 13X packed GC column uses a 45/60-mesh zeolitic adsorbent in a preconditioned nickel tube. The column measures 10 ft (3.05 m) in length, 1/8 in. outside diameter and 2 mm inside diameter. Molecular-sieve packing is suited to gas separations requiring size- and adsorption-dependent retention, but the adsorbent is highly sensitive to water and some strongly retained components. Plan sample pretreatment and analytical sequencing to limit moisture loading and prevent irreversible contamination. The higher adsorption strength and 45/60-mesh packing should not be confused with the HayeSep Q polymer column, even though both products share similar tube dimensions. Install with compatible packed-column fittings, perform a carrier-gas leak test and establish an appropriate activation or conditioning sequence for the intended analysis. Verify resolution of the target gases with a certified standard and monitor retention shifts that may indicate adsorbent deactivation or moisture exposure.
