HPLC Analysis of Solvent Yellow 124—The Marker in Diesel Oil
A method for the analysis of Solvent Yellow 124, a new marker added in diesel oil and sold in Sweden is presented. The method we describe involves analysis by HPLC on a normal phase column.
The diesel samples were injected directly onto the column. No enrichment of the marker prior to analysis was necessary and quantitative analyzing was possible at concentrations above 0.05 mg/L. The quantitative analysis was improved by the use of an internal standard (Pigment Yellow 3). The use of toxic solvents in the mobile phase was avoided.
