Agilent, CP7489, J&W CP-Sil 88 for FAME GC Column, 100 m, 0.25 mm, 0.20 µm, 7 inch cage

The Agilent J&W CP-Sil 88 for FAME capillary gas chromatography column is a highly polar fused-silica column designed for separating fatty acid methyl esters, particularly positional and cis/trans isomers. The capillary is 100 m long, has a 0.25 mm internal diameter and a 0.20 µm stationary-phase film, supplied on a 7-inch cage. The long column and selective polar phase help resolve complex mixtures in food oils, lipids and other FAME analyses, although resolution depends on the sample and GC method. The stated operating temperature range is 50 °C to 225 °C, with a higher programmed limit of 240 °C where applicable. Install the column using the correct ferrules, trim the capillary ends cleanly and check for leaks before conditioning it. Select an injection scheme and oven program compatible with both the phase limits and analyte volatility. Use qualified FAME standards to identify critical isomers and establish response and resolution. The column is an analytical separation consumable, not an FAME derivatization reagent.
