What is Azo Dye Detection in Paprika by GC-MS about?

This study developed and validated a gas chromatography-mass spectrometry (GC-MS) method for simultaneously detecting 23 azo dye breakdown products and one azo dye (disperse orange 3) in paprika samples. The method involved extracting the dyes from paprika using dichloroethane, separating the compounds on an Agilent J&W DB-5ms Ultra Inert capillary column, and detecting them using GC-MS. The method was accurate (90-104% recovery) and precise (RSD below 4.6%) for quantifying the dyes at concentrations of 2.4
