This application note describes how to use Agilent J&W FactorFour VF-5ht Ultimetal column for high temperature gas chromatography analysis of synthetic petroleum products.
The document details the use of the Agilent J&W FactorFour VF-5ht UltiMetal column for analyzing Fischer-Tropsch reaction products, which include long-chain hydrocarbons up to C100. The analysis requires oven temperatures reaching 440 °C to elute these high-boiling fractions effectively.
Oven temperatures up to 440 °C are required to elute the C90 to C100 hydrocarbon fraction.
The column maintains excellent resolution and peak profiles after 500 analysis cycles equaling a 125 hour exposure to 440 °C.
The column used in the analysis is 30 m long with an inner diameter of 0.32 mm.
