Agilent, 19091P-QO4, J&W HP-PLOT Q GC Column, 30 m, 0.32 mm, 20.00 µm, 7 inch cage

The Agilent J&W HP-PLOT Q gas chromatography column is a porous-layer open tubular fused-silica column designed for the separation of light gaseous and volatile compounds. It measures 30 m in length, has a 0.32 mm internal diameter and carries a 20 µm porous stationary layer. The HP-PLOT Q bonded porous-polymer phase is relevant to analyses of light hydrocarbons and selected permanent or polar gases, such as carbon dioxide, hydrogen sulfide and low-molecular-weight solvents, depending on the configured method. Porous-layer selectivity differs substantially from the liquid stationary-phase behavior of conventional nonpolar GC columns. The exact temperature specification is −60 °C to 270 °C, with a 290 °C programmed-temperature maximum. Because PLOT phases can be sensitive to contamination or unusual pressure transients, follow the manufacturer's conditioning and column-handling procedure and use appropriately clean carrier gas. Install the column with suitable fittings, avoid particles entering valves or detectors and confirm separation performance with the method's calibration mixture. The product is supplied in a 7-inch GC cage.
