一般描述

Ponceau SX is classified as a synthetic food color, widely used for the maintenance and improvement of color appearance in foods.

应用

Ponceau SX may be used as a reference standard for the determination of the analyte:
  • In cosmetic products by micro-matrix solid phase dispersion and liquid chromatography coupled to tandem mass spectrometry.
  • In foodstuffs by combining high performance liquid chromatography (HPLC) with diode array detection (DAD) and ion-trap time-of-flight mass spectrometry (IT-TOF/MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

包装
