Agilent, G3591-82001, J&W GC packed column in Nickel tubing, length 15 ft (4.57 M), 1/8 in. OD, 2 mm ID, 25% DC-200 on Chromosorb PAW packing, mesh size 80/100, pre-conditioned

The Agilent J&W packed GC column contains 25% DC-200 stationary phase supported on 80/100-mesh Chromosorb PAW. Its preconditioned nickel tubing is 15 ft (4.57 m) long with a 1/8 in. outside diameter and 2 mm internal diameter. The DC-200 liquid phase provides gas–liquid partition selectivity suited to appropriately validated volatile-compound methods. The 15 ft length can contribute additional separation opportunity compared with shorter packed beds, but may also raise pressure drop and analysis time; select carrier-gas conditions accordingly. Confirm that the GC oven has sufficient space and that the injector and detector accept the packed-column fittings and nickel-tube geometry. Before routine analysis, leak-test the assembly and use a reference standard to evaluate retention, peak symmetry and baseline stability. Avoid temperatures beyond the supported phase operating limit, and prevent oxygen or sample residue from accelerating stationary-phase deterioration. The column is not a direct substitute for a capillary column or another DC-200 loading.
