Determination of benzothiazole and benzotriazole derivates in tire and clothing textile samples by high performance liquid chromatography–electrospray ionization tandem mass spectrometry

• Benzothiazoles and benzotriazoles were determined in a textile and a tire sample.
• Ultra-sonication assisted solvent extraction for these compounds was developed.
• Liquid chromatography electrospray ionization–tandem mass spectrometry was used.
• Matrix effects, extraction recoveries and limits of detection were evaluated.

A high performance liquid chromatography–tandem mass spectrometry method utilizing electrospray ionization in positive and negative mode has been developed for the separation and detection of benzothiazole and benzotriazole derivates. Ultra-sonication assisted solvent extraction of these compounds has also been developed and the overall method demonstrated on a selected clothing textile and an automobile tire sample. Matrix effects and extraction recoveries, as well as linearity and limits of detection have been evaluated. The calibration curves spanned over more than two orders of magnitude with coefficients of correlation R2 > 0.99 and the limits of detection and the limits of quantification were in the range 1.7–58 pg injected and 18–140 pg/g, respectively. The extraction recoveries ranged between 69% and 102% and the matrix effects between 75% and 101%. Benzothiazole and benzotriazole derivates were determined in the textile sample and benzothiazole derivatives determined in the tire sample with good analytical performance.
