METHOD USED FOR RAPID TESTING OF HIGHLY VOLATILE SUBSTANCES OF VERY HIGH CONCERN IN TEXTILES

摘要

This invention provides a method for rapidly detecting volatile substances of very high concern (SVHCs) in a textile. Based on the ion mobility spectrometry technique, this method may achieve rapid detection of 11 kinds of volatile SVHCs within 1-6 minutes, respectively, by means of direct introduction of textile samples or in combination with an efficient and convenient solvent extraction pretreatment step. The detection limit is less than 100ppm, which absolutely satisfies the mass fraction limit of 1000ppm prescribed in REACH Regulation of the European Union. This method may greatly shorten detection periods of these volatile organics and enable the possibility to realize online detection for these substances.
