Agilent, CP7654, J&W CP-Wax 58 FFAP CB GC Column, 25 m, 0.53 mm, 2.00 µm, 7 inch cage

Agilent J&W CP-Wax 58 FFAP CB is a high-polarity fused-silica GC column measuring 25 m × 0.53 mm with a 2.00 µm bonded stationary-phase film. FFAP-type selectivity is useful for gas chromatographic separations of free fatty acids and other polar or acidic volatile organic compounds. The wide-bore, thick-film format gives laboratories an option for volatile analytes requiring polar retention while using a conventional 7-inch column cage. The column has a specified temperature range of 20 to 250/275 °C. Its acidic/polar selectivity differs substantially from nonpolar DB-5 phases, so retention patterns and elution order should not be assumed equivalent. Method development should consider sample volatility, solvent compatibility, carrier-gas flow and thermal limits appropriate to the FFAP phase.
