This document describes the method of diesel analysis using the Agilent J&W FactorFour VF-5ht UltiMetal column. The column is developed using proprietary UltiMetal technology, which provides a virtually unbreakable metal column material with excellent inertness properties similar to fused silica tubing. The UltiMetal column tubing is coated with the VF-5ms low bleed arylene stabilized liquid phase, resulting in a highly temperature stable and durable column perfectly suited for a variety of high temperature applications.
The document details a gas chromatography (GC) method for analyzing diesel fuel. It highlights the use of the VF-5ht UltiMetal column, which features proprietary technology providing excellent inertness and durability at high temperatures due to its arylene stabilized liquid phase coating.
Specific operating conditions are provided, including the use of hydrogen as a carrier gas, split injection mode, and a temperature program ranging from 50 °C to 400 °C. The method utilizes an FID detector set to 340 °C.
The analysis uses Hydrogen as the carrier gas at a pressure of 65 kPa (9 psi).
The temperature is ramped from 50 °C to 400 °C with a rate of 5 °C/min.
