The main innovation lies in the systematic validation of TD\u2010GC\u2010C\u2010IRMS for atmospheric VOC analysis, which enables reliable \u03b4\n                    <jats:sup>13<\/jats:sup>\n                    C determination with minimal isotopic bias. The optimal TD conditions were 300\u00b0C and 5\u2009min. Advantages include high precision (SD\u2009\u2264\u20090.4\u2030), good reproducibility, long\u2010term sample stability (up to 50\u2009days), and suitability for on\u2010site air sampling. Limitations are the coverage of only seven compounds and a wider range of VOC species and more complex matrices should be addressed in future work. The method was successfully applied to ambient air samples, and isotopic signatures indicated that VOCs were mainly derived from traffic\u2010related emissions. This approach provides a robust and practical tool for source identification of atmospheric VOCs and supports source apportionment studies in environmental research.\n
