Descrição geral

Naphthol Yellow S is a dye that is known for its hazardous nature.

Aplicação

Naphthol Yellow S may be used as an analytical reference standard for the determination of Naphthol Yellow S in:
  • Foodstuffs by solid phase extraction (SPE) and high performance liquid chromatography (HPLC)-diode array detection (DAD)-ion trap time-of-flight tandem mass spectrometry (IT-TOF-MS3) equipped with multiple reaction monitoring (MRM) detection.
  • Drinks and candies by SPE followed by analysis using HPLC coupled to photodiode array (PDA) detector.
  • Wastewater samples by adsorption column chromatography.
  • Embroideries designed by the famous 19th century French painter Emile Bernard.
