GC-MS method for regulated Chlorinated Organic Carriers (COCs)Analysis: A streamlined and authenticated GC-MS method for the simultaneous analysis of all regulated Chlorinated Organic Carriers

This study introduces a novel method for the simultaneous identification and quantification of extractable chlorinated organic carriers (COCs) from textiles, foam, and leather. Using dichloromethane under ultrasonic conditions at 25°C for 30 minutes, COCs were effectively extracted and analyzed via gas chromatography-mass spectrometry (GC-MS) with a DB-5MS column. The optimized method achieved high recoveries (95–105%), excellent precision (RSD <10%), and a low detection limit (<0.1 ng mL⁻¹). Real specimen analysis confirmed COCs at 2.60–9.94 ng mL⁻¹, highlighting the method’s potential for environmental monitoring and risk assessment.
