Application: Tartrazine may be used as a reference standard in the determination of tartrazine in food samples using ion-pair liquid chromatography coupled with photodiode-array and electrospray mass spectrometry detector.
The application of Tartrazine is seen in the phloxine-tartrazine procedure for cellular inclusions such as viral aggregates and eosinophil granules. It may be used as a substitute for orange G in a variant of Mallory′s trichrome, and in a methyl violet-tartrazine mixture to stain cryptosporidia in faecal smears and mucosal scrapings.
