Restek, 10642, Stabilwax GC Capillary Column, 60 m, 0.32 mm ID, 0.50 µm

The Restek Stabilwax capillary GC column uses a polar, bonded polyethylene glycol stationary phase designed for separation of oxygenated, aromatic and other compounds that require wax-phase selectivity. Its analytical dimensions are 60 m length, 0.32 mm inner diameter and a 0.50 µm film thickness. The long column format can provide increased separation opportunities for complex sample mixtures, while demanding attention to carrier-gas pressure and analysis time. Representative applications include solvent profiling, flavor and fragrance analysis, fatty acid methyl esters, and selected alcohol, aldehyde or aromatic isomer methods. Establish an oven program and injection mode that maintain acceptable peak shape while respecting the specified 40 to 250/260 °C operating range. Use clean carrier gas, avoid oxygen ingress during heating and follow conditioning instructions before chromatographic evaluation. The bonded polar phase can tolerate suitable solvent rinsing during maintenance, but cleaning must follow manufacturer's compatibility recommendations. This is a capillary GC separation column, not an HPLC column or an uncoated transfer line.
