This report summarizes method development for the identification of polyterephthalates using simultaneous pyrolysis methylation‐gas chromatography with mass spectrometry. Ground detergent products are directly pyrolyzed together with the methylation reagent tetramethylammonium hydroxide. Key fragments separated via gas chromatography are detected by a mass selective detector. Trace levels of polyterephthalates in laundry detergent products were identified within 20 min without interference from surfactants or other organics. Detection limit was 0.05% by weight in product.
