Agilent, CP7525, J&W CP-TCEP for Alcohols in Gasoline GC Column, 50 m, 0.25 mm, 0.40 µm, 7 inch cage

The Agilent J&W CP-TCEP for Alcohols in Gasoline column is a specialized capillary GC phase for separating oxygenated components in gasoline matrices. It uses a 50 m fused-silica capillary, 0.25 mm internal diameter and 0.40 µm stationary-phase film on a 7-inch cage. The distinctive polar selectivity supports analysis of alcohols and relevant aromatic hydrocarbons in established fuel-testing methods, including applications associated with ASTM gasoline procedures. Column selection and oven programming are especially important because the CP-TCEP phase has a comparatively narrow temperature operating envelope; avoid transferring a high-temperature program developed for a different GC column. Install in a compatible instrument, check for leaks and condition within the manufacturer's permitted temperature limits. Run a gasoline-related reference standard to confirm component resolution and retention order before quantifying unknown mixtures. Keep inlet consumables clean, avoid sample overload and apply method-specific calibration for reliable alcohol measurement.
