Answer:Potassium-chloride-modified alumina (Al₂O₃/KCl) in a porous-layer open tubular GC format.
Answer:The column is 30 m long with 0.53 mm inner diameter, a 15 µm porous layer and a 7-inch cage.
Answer:Adsorption changes at the alumina surface can alter retention, peak shape and analytical reproducibility.
The Agilent J&W HP-PLOT Al₂O₃/KCl gas chromatography column uses a porous-layer open tubular (PLOT) alumina stationary phase modified with potassium chloride. Its 30 m fused-silica tube has a 0.53 mm internal diameter and a 15 µm porous layer, supplied on a 7-inch cage. Adsorptive PLOT selectivity is useful for separating light hydrocarbons and related gas mixtures that may be poorly retained on conventional liquid-film capillaries. Control moisture, strongly retained contaminants and particulate entry because they can change the alumina surface and reduce chromatographic performance. Use appropriate carrier-gas flow and temperature programming, and establish a baseline with a gas standard before injecting samples. The alumina/KCl surface is chemically and chromatographically different from molecular-sieve packed beds and low-polarity HP-PONA films; those columns should not be treated as interchangeable. Follow approved conditioning and operating-temperature limits to protect retention stability and column life.
