General description

Solvent Yellow 124 is a marker dye, generally used in diesel oil as a green colorant, which can be analyzed using high performance liquid chromatography method (HPLC). It is mainly used to prevent the misuse of low tax diesel fuel and as to also calculate the adulteration of road fuel with low tax diesel fuel.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Solvent Yellow 124 may be used as an analytical reference standard for the quantification of the analyte in diesel samples using high performance liquid chromatography with UV/Vis spectrophotometric detection and fluorescence spectroscopy/chemometrics.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
