Determination of Aromatic Hydrocarbons in Jet Fuel by LC-RID According to ASTM D6379 / IP436 using a Two-column Set

Introduction

The test method presented here is applicable to the determination of mono- and di-aromatic hydrocarbon content in aviation fuels and middle distillates with boiling points in the range of 50° C to 300° C in accordance with ASTM D6379 and IP436. This application is relevant to some of the most commonly-used aviation fuels, such as Jet A and Jet A-1. The accurate determination of the aromatic content of fuels is critical to assessing their quality and combustion characteristics. These parameters are crucial to ensuring aviation safety and compliance with environmental regulations. This methodology presents an alternative to ASTM D1319. Though ASTM D1319 has enjoyed widespread use, it relies on the use of a fluorescent dye which was discontinued, and the replacement no longer produces reliable results, particularly for middle distillates. As such, many laboratories are exploring alternative methods, including ASTM D6379 / IP436, for determination of the total aromatics in kerosene and jet fuels. This application news demonstrates the use of the Shimadzu Prominence HPLC for the determination of mono- and di-aromatic hydrocarbons in aviation fuel and other middle distillates in compliance with parameters set out in ASTM D6379 and IP436. Due to the use of a two- column set, the instrument is also in compliance with ASTM D6591 with minimal changes to the instrument configuration.
