ZHTest Method: SATRA TM459
The Quantitative Analysis of Disperse Dyes by LC-MS
December 2020
SCOPE
This method is intended to determine the amount of certain disperse dyes in textile materials using liquid chromatography with triple quadrupole mass spectrometry (LC-MS/MS) as the quantification technique. This method is primarily applicable to textiles, although leathers can also be assessed using this method if required.
PRINCIPLE
Some disperse dyes are known to have the potential to cause an allergic reaction when in contact with the skin whilst others are suspected carcinogens, hence specific named disperse dyes are regularly listed on restricted substances lists.
A textile material is extracted in methanol by way of ultrasonic action. The extract is then filtered into sample vials and analysed quantitatively by LC-MS/MS using a multiple reaction monitoring (MRM) method. The content of disperse dyes in the material is calculated in mg/kg.
