Case Study

High-Throughput Detection Method of Disperse Yellow 49

Zhou Y, et al. Talanta, 2014, 127: 108-115.

Disperse Yellow 49 is a disperse dye. Disperse dyes are non-ionic dyes with low water solubility and mainly exist in dispersed form of tiny particles during dyeing. The rapid development of new dyeing technologies for polyester fibers and disperse dyes has led to the widespread use of disperse dyes in textiles. High-performance liquid chromatography-tandem mass spectrometry is a common detection method for disperse yellow 49.
High-throughput detection methods:
Ultra-high performance supercritical fluid chromatography-tandem mass spectrometry (UHPSFC-MS/MS) systems are an alternative method for rapid analysis of multiple dyes. Up to 17 disperse dyes can be analyzed simultaneously using UHPSFC-MS/MS, with simultaneous separation and determination in less than 5 minutes.
