Separation Science, in collaboration with Agilent, offers a video application and complementary application note focused on the analysis of a newly introduced fuel marker in diesel fuel by 2-dimensional GC/MS with the use of hydrogen as the carrier gas.
Fuel marking is an authentication method used by governments to ensure that the national fuel supply comes from a legal source and complies with regional standards. It is necessary to have a solid method to deter illegally traded fuel. At the same time, laboratories are reducing their helium dependence because of its high cost, and they require methods that use alternative carrier gases without sacrificing chromatographic performance.
This application demonstrates the analysis of a newly introduced fuel marker in diesel fuel by 2-dimensional GC/MS with the use of hydrogen as the carrier gas. A capillary flow technology (CFT) Deans switch is used to provide a robust and sensitive analytical solution for the detection and quantitative analysis of the fuel marker. It allows analysis down to low mg/L levels by direct injection of diesel fuel, to comply with all regional regulations.
Agilent GC/MSD setup enables fuel marker quantification for both marking level control as well as low-level analysis for fraud detection. Agilent could install the application on helium and hydrogen carrier gas, where hydrogen is particularly appealing if your laboratory would like to overcome the helium price and potential shortages.
