Agilent, 19095P-M25PT, J&W HP-PLOT Al2O3 M PT, 50 m, 0.53 mm, 15 µm GC column, , with two particle traps (front and rear)

The Agilent J&W HP-PLOT Al₂O₃ M Gas Chromatography Column is a porous-layer open-tubular capillary column developed for separation of light hydrocarbons and closely related volatile isomers. This configuration is 50 m long with a 0.53 mm internal diameter and a 15 µm alumina-based porous stationary layer. It includes two particle traps, positioned at the front and rear, to help capture stationary-phase particles that might otherwise migrate into connected GC hardware. The column has a nominal operating temperature range of −60 to 200 °C and is supplied in a standard seven-inch format. Its alumina selectivity can be useful where separation of low-molecular-weight hydrocarbon components is required. Use the appropriate carrier gas, flow conditions and inlet arrangement, and avoid introducing nonvolatile sample residues that could contaminate the porous bed. The integrated particle traps distinguish this configuration from the otherwise similar column sold without traps. It is not a packed GC column or a general-purpose liquid chromatography column.
