Agilent, G3591-82000, J&W GC packed column in Nickel tubing, length 2 ft (0.61 M), 1/8 in. OD, 2 mm ID, 12% UC W982 on Chromosorb PAW packing, mesh size 80/100, pre-conditioned

The Agilent J&W packed GC column uses 12% UC W982 stationary phase coated on 80/100-mesh Chromosorb PAW support. The packing is contained in a preconditioned nickel tube 2 ft (0.61 m) long with 1/8 in. outside diameter and 2 mm inside diameter. The coated support supplies a liquid stationary phase for gas–liquid partition chromatography, making the phase chemistry and sample compatibility central to method selection. This compact packed format is distinct from the longer HayeSep Q and molecular-sieve columns, which use different separation mechanisms. Install the column using fittings and carrier-gas flow appropriate to the GC system, then check the assembly for leaks. Stabilize at an approved method temperature before evaluating retention time, response and repeatability with reference compounds. Avoid treating preconditioning as confirmation that a particular sample matrix or oven program will be suitable. Preserve the phase by following the applicable maximum-temperature and carrier-gas recommendations.
