Volatile Organic Compounds (VOCs) are organic chemicals with high vapor pressure, originating from natural and anthropogenic sources, and are major contributors to environmental issues like photochemical smog and atmospheric pollution. This study introduces an optimized TD-GC-MS method for detecting and quantifying VOCs in ambient air, employing internal standards and certified reference materials to ensure analytical accuracy and traceability. The method is designed to deliver exceptional sensitivity, precision, and reproducibility, suitable for diverse environmental conditions. Key improvements include optimized thermal desorption, fine-tuned chromatographic separation, and calibrated mass spectrometric detection. Aligned with Eurachem guidelines, the integration of internal standards mitigates instrumental variability, while certified reference materials ensure traceable calibration, enhancing result reliability. The research demonstrates the method's applicability to air quality monitoring, environmental assessments, and public health research. The findings validate TD-GC-MS as a robust, reliable solution for continuous VOC monitoring and routine environmental applications, providing critical insights into pollution sources and impacts, particularly in urban and industrial contexts. This research addresses the needs of scientists, policymakers, and environmental professionals seeking effective tools to combat air pollution.
