This application note provides a detailed description of the method to analyse carnauba wax using the Agilent J&W FactorFour VF-5ht UltiMetal column
Carnauba wax is widely used in cosmetics, polishes, and food products due to its glossy finish. The document details how the Agilent J&W FactorFour VF-5ht UltiMetal column is ideal for analyzing this wax because of its proprietary UltiMetal technology, which offers excellent inertness and high temperature stability similar to fused silica tubing. The column's low bleed characteristics allow for the accurate quantification of minor high boiling impurities found in the wax esters ranging from C46 to C54.
| Column Dimensions | 15 m x 0.32 mm |
|---|---|
| Film Thickness | 0.1 um |
| Retention Gap Dimensions | 2mx 0.53 mm |
| Injector Temperature Program | 100 °C (0 min) to 400 °C |
| FID Temperature | 400 °C |
The VF-5ht UltiMetal column is ideal for the analysis of carnauba wax.
The C46—C54 wax esters elute in the 275 °C to 400 °C temperature range.
