GC-MS method for regulated Chlorinated Organic Carriers (COCs)Analysis

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.
